Is Rigol DS1102E a Good Deal?
The answer is definitely yes. This 100 MHz digital oscilloscope is one of the best entry-level digital storage oscilloscopes (DSOs) that ever came out. Although it is not as nice as the expensive ones, it gives functionality, design and robustness per dollar better. This scope is good for general purpose measurement. For someone with a small budget, the Rigol DS1102E nails the basic function most hobbyists and students require and more.
It has 2 analog input channels and one more for external trigger. Real-time sampling rate is at 1 GSa/s when acquiring signals on one channel alone and gets 500 MSa/s when both channles are used. Vertical range is at 2mV/div – 10V/div and has the basic addition, subtraction, multiplication and FFT math functions. Run-time values can also be enabled to get a quick read on the running voltages in the signals. The buttons and knobs are robust enough for everyday wear and tear. It’s logically arranged so the user is not lost when using it. It also has a PC software suite for remote control and acquisition. It has the auto function that automatically adjusts and displays the signal being acquired. And just like Tektronix DPO2000B, it has cursor functions such as manual, track and auto measurement modes; this feature makes it at par with more expensive models of its class.
Instrument drivers of the DSO are available in National Instrument’s device driver network which makes it even more popular for students learning LabVIEW and professional engineers looking for a cheap solution for some auto-bench measurement problems. The readily-available driver gives this oscilloscope a professional feel but ultimately it provides convenience for those who aims to control the instrument using LabVIEW. The USB and RS-232 interface makes for a cheap type of automated control of the instrument. Most models of the same design do not have the RS-232 port making it functionally better than other models with 5X the cost.
Due to its popularity, the model has developed a huge user community that can help in promoting the model and also troubleshooting in case breakdown occurs. A huge fan base so to speak is a great help especially for feedbacks for those who are planning on buying it. The automation and software control and PC application development is what makes the huge fan base most advantageous. Users of this 100 MHz digital oscilloscope can make use of a number of resources about the scope and also samples of programs and source codes that can optimize its use.
With this scope’s portable size, it’s a little wonder how such equipment could pack so many features. The screen resolution is a bit lower compared to other models (320X320) but the color-coded signal per channel makes up for that. The sweep cursor function also display voltage levels while passing through parts of the waveform. The FFT function produces waveforms with lower resolution (disadvantageous if one is looking for frequencies or events such as glitches and sudden peaks) compared to professional brands like LeCroy but this is an o-scope bought at the fraction of the price. The FFT function might be good only for resonance frequency readings and events with lower frequency.
For someone who has used professional oscilloscopes of the same class, not much difference can be seen. Expensive brands usually cramp more features into their products which ends up unused by the customer. For an instrument that is designed for portability, a feature that measures signals in the GHz bandwidth is too much. And most oscilloscopes of the same class would add a few more bucks just to get an interface for remote control.
More value for money, this is the screaming advantage of Rigol DS1102E. Its operational function is logical and comes with a solid feel that rarely comes with a product this cheap. You can view the product's information on www.rigolna.com

Passive Probe Types- An Overview
Voltage probes used in oscilloscopes are typically classified as active and passive probes. Passive probes are so named because it is indicative of the fact that this type of probe does not contain active elements like transistors inside them. Rather, a probe of this kind consists entirely of passive elements like resistors, inductors, cables and capacitors. Because of this, it is unable to provide amplification and thus it only gives the original signal amplitude of a material being tested to the measuring instrument.
One advantage of using passive probes on an oscilloscope is that there is no hard limit for the maximum voltage that the probe is able to handle. It is also an inexpensive option since its circuitry is relatively simple and it does not require a power supply. In addition to that, its passive nature prevents the addition of random noise to the signals being sent to the oscilloscope. Majority of probes used in oscilloscopes are of the passive kind.
Passive probes are typically categorized based upon the level of attenuation of the signal that the probes can provide. There are typically three classifications of passive probes each one depending on the attenuation ratio. Attenuation refers to the gradual loss of intensity of any type of flux that is travelling through a medium; in this case, the flux is the voltage of the circuit being tested. These types are generally 1X, 10X and 100X probes.
A 1X scope probe provides a 1:1 attenuation ratio. It is the simplest oscilloscope probe. As suggested by its name, this probe does not attenuate the voltage going through it. Its impedance input is oftentimes similar to that of the oscilloscope. This type of passive probe is made of a connector to the oscilloscope and a coax that is connected to actual probe. A 1X probe is mostly suited for low frequency applications. However, applications requiring greater accuracy and higher frequencies may not be suited for this type of probe.
Better accuracy at higher impedance levels are achieved more using 10X scope probes. This type of probe has attenuators attached to its end that can then connect to the circuit being tested. A 10X probe indicates that the probe attenuates the incoming voltage by a factor of ten. Technically, the signals entering the oscilloscope are reduced and this factor must therefore be taken considered when making measurements.
The third most common probe is 100X scope probes. Other values such as 20X and 1000X probes are also available but the 100X is the most popular choice after the 1X and 10X probes. This passive probe is useful when taking measurements of circuits with extremely high voltages as well as those circuits that need very low levels of loading. These probes are typically used for special purposes and are not commonly utilized for the average application. Because it attenuates the signal by a factor of 100, utilizing it in normal applications will result to significantly minute signal levels being input to the oscilloscope. As a result, extraneous and unwanted noise on the input amplifiers of said scope will be visible and this could lead to inaccuracies in the readings.
The types enumerated above are just some of the most common types of passive probes. Oftentimes, the task of choosing the best probe for an oscilloscope will depend on what is readily available. Being familiar with the requirements of the test as well as the specifications of the circuit to be tested are also vital in determining the most appropriate probe for the job. Basic knowledge of the different passive probe types however will go a long way in ensuring good and accurate results.

Agilent 1130a Oscilloscope - Functions and Specifics
In a nutshell, the oscilloscope is an electrically sensitive device that is used to measure the voltage across an electronic device or a circuit. Unlike a regular voltmeter, that measures static voltage, this device measures and continuously plots voltage against time. The display of the device has an x-axis for the time and y-axis for the voltage. The reading deflects upwards with a positive voltage input and it goes down with a negative voltage input. The Agilent 1130a Oscilloscope in particular, is a high-frequency “active differential” oscilloscope.
The name of the device has an etymological root of “oscillation” which means “back and forth deflection.” This is characterized by the movement of the readings. There are analog and digital types of the device. Nowadays, the digital types are widely used because of their high sensitivity, memory and processing capacity. To measure signals and voltage, the “probe” or sensor of the 1130a Oscilloscope must be connected to a live circuit.
Perhaps the most convenient feature of the 1130a Oscilloscope is the support for variable probe heads. The probes are directly placed on the circuit to measure signals, voltages and resistances. However, modern technologies have smaller circuit boards and tight spaces. Traditional probes cannot fit or correctly connect with the right spot.
The new trend is the usage of differential SMA heads. Ergonomically designed, the span of these sensors can be adjustment in just a few simple steps. With these variable probe heads, human-caused errors and equipment damages can be minimized. This feature makes the 1130a a versatile measuring equipment for applications in electronics, physics and engineering – both in small and large-scale tasks.
The 1130a Oscilloscope, like other active differential models (1131a to 1132a) have probe systems with various bandwidths. The bandwidth, briefly, is the amount of signal that a probe can handle against time. The probes come in 7, 5, 3.5 and 1.5 gigahertz types. Modern probes like these demonstrate across the entire bandwidth a flat frequency response. This results in less distortion when measuring different ranges of voltages.
The best feature of these modern oscilloscopes is the dual support for single-ended and differential measurements. You will only to need to change the probe or accessory depending on the circuit to be examined.
The 10%-90% rise and fall time of the 1130 is very fast at 233 psec. The bandwidth of the probe is greater than 1.5 GHz. The input dynamic range is between -2.5 and +2.5 volts.
For more information on the Agilent 1130a oscilloscope, you may visit the manufacturer's website and look for the schematic diagram of the device. Before purchasing, check on the different capacitance levels, induction, resistance and -3 DB system bandwidth of the device. While oscilloscopes function in a more or less common way, some designs are more ergonomic and efficient. This may sound like a no-brainer, but you must choose an oscilloscope that safely fits the voltage/signal range of the device to be measured.
