PicoScope 9200采樣示波器與常規數字存儲示波器有什么不同?
All digital storage oscilloscopes (DSOs) work by sampling the input signal. The standard type of DSO uses “real-time sampling", which is illustrated in Fig. 1. Fig. 1 – Real-time sampling. (a) The original signal. (b) The scope samples the signal in several places. (c) The samples are stored in memory. (d) The scope reconstructs the signal using the stored samples. (Straight-line interpolation is shown here, but other methods exist.) A sampling oscilloscope is a special type of DSO that exclusively uses a technique called “sequential equivalent-time sampling" or just “sequential sampling". This type of sampling is best suited to repetitive waveforms such as serial data streams, clock waveforms and pulses in digital circuits, some of the data patterns used in semiconductor testing, and amplifier pulse-response and rise-time tests. A sampling scope captures just one sample from one cycle of the waveform and then repeats the process over a large number of cycles, varying the timing of the sample in a known pattern from one sample to the next. The resulting collection of samples is then assembled into a picture of the whole waveform. | | Fig. 2 – Sequential sampling. (a) One sample is taken from each of a number of similar waveforms. (b) The samples are assembled to form a composite waveform. |
The advantage of a sampling scope is that its analogue-to-digital
converter (ADC) only needs to be fast enough to capture one
sample in each cycle of the waveform, rather than the tens or
hundreds of samples that a real-time scope would require. This
allows the scope to capture waveforms with much higher
bandwidths, up to 12 GHz in the case of the PicoScope 9201A/9211A,
ａnd to capture each sample with higher precision. A real-time
DSO that could capture a single cycle of the same 12 GHz
waveform would be prohibitively expensive. For example the
12 GHz Agilent DSO91204A, with a real-time sample rate of
40 GS/s, has a base price of $96,000 – 8 times the price of the
PicoScope 9201A/9211A.
PicoScope 9201A/9211A是一個數字信號分析儀(DSA)嗎?
Yes. Some manufacturers use that term for sampling scopes that are aimed at the digital signal market. We chose to call the PicoScope 9201A/9211A a sampling oscilloscope because it can do more than just measure digital signals: it can also be used to analyse repetitive analogue waveforms.
實時采樣率和等效采樣率之間有什么不同?
The real-time sampling rate of an oscilloscope is the rate at which its ADC can reliably sample the input waveform. If you wish to capture a single event such as a one-off glitch in a digital circuit, then the oscilloscope has only one chance to acquire enough samples to represent the waveform accurately. In such cases, there is no substitute for an oscilloscope with a high real-time sampling rate. A common rule of thumb is that at least 10 samples are needed for each cycle of the waveform. For example, if the signal in question is a 2 GHz square wave, then a scope with a real-time sampling rate of at least 20 GS/s would be needed to capture a realistic-looking picture. For accurate analysis of the timing and shape of the waveform, as required in mask testing, several hundred samples are needed. This would entail a real-time sampling rate of 200 GS/s or more, which is beyond the capabilities of today's off-the-shelf instruments and, even if such a scope existed, it would be prohibitively expensive. The equivalent-time sampling (ETS) speed of a scope is not a measure of the speed of its ADC, but an estimate of the speed of an imaginary ADC that could capture a single-shot waveform at the same timebase, and with the same number of samples, as the sampling scope in question. If a sampling scope had perfectly accurate timing, then it could achieve an ETS rate as large as you wished just by waiting for the necessary number of cycles of the input waveform to pass by. In real life, however, the ETS rate of the scope is limited by the timing and trigger circuitry. The smaller the timing uncertainty (called jitter), the more non-overlapping samples the scope can take to form the final picture, and therefore the higher the equivalent-time sampling rate. Thanks to its low jitter, the PicoScope 9201A/9211A has a maximum ETS rate of 5 TS/s. Many of today's DSOs list both real-time and equivalent-time, or sequential, sampling rates in their specifications. When choosing an oscilloscope, you need to make sure that both sampling rates are adequate for your application.
我能把PicoScope 9201A/9211A用作常規測試和測量項目嗎?
The PicoScope 9201A/9211A is not intended to replace the general-purpose oscilloscope on your workbench. The main differences between the PicoScope 9201A/9211A and a general-purpose scope are as follows: SMA input connectors . General-purpose scopes usually have BNC connectors on their inputs, but these connectors do not have a well-defined impedance above about 2 GHz. SMA connectors are better suited to high-frequency signals and are widely used in microwave applications. 50 ohm inputs . The PicoScope 9201A/9211A has low-impedance inputs that do not work with passive high-impedance scope probes but work well with low-impedance probes. The low input impedance is necessary to match the scope to standard high-frequency signal cables and connectors without causing reflections. Most instruments designed for signals above about 500 MHz have input and output impedances of 50 ohms. ±2 volt safe input range . The sensitive, high-bandwidth input circuitry of the PicoScope 9201A/9211A does not allow the same wide range of input voltages as found on a general-purpose scope. If your signal is larger than ±1 volt (the maximum measuring range) then you must use an external attenuator. You must also protect the inputs against electrostatic discharges. 100 kS/s real-time sampling . The PicoScope 9201A/9211A is not designed to be used as a real-time sampling oscilloscope. Its precision ADC is optimised for equivalent-time sampling with very low jitter, allowing an equivalent-time sampling rate of up to 5 TS/s for repetitive signals. Dedicated software . The software supplied with the PicoScope 9201A/9211A is designed to work only with sampling oscilloscopes. It contains advanced display features such as eye diagrams and histograms, and specialised measurements and industry-standard mask tests that do not apply to real-time oscilloscopes. This software is very different from PicoScope 6, our general-purpose oscilloscope software, in both appearance and function, and data files cannot be exchanged between the two programs.
直接觸發和HF觸發輸入之間有什么不同?The Direct Trigger is a full-function trigger input with a bandwidth of 1 GHz, and is applied
directly to the trigger circuitry. This input allows variable slope, hysteresis and trigger level.
The HF Trigger input passes through an internal prescaler before being applied to the trigger
circuitry. This input has a higher bandwidth, up to 10 GHz, but lacks the adjustments available
on the Direct Trigger input.
| | Fig. 3 – Histogram. A vertical histogram shows the signal density as a function of voltage, and helps to visualise noise. |
柱狀圖功能用來做什么?The PicoScope 9201A/9211A can collect large numbers of waveforms
ａnd perform statistical analysis on them. The results of the
analysis can be displayed as histograms against voltage
(vertical histograms) or time (horizontal histograms).
A vertical histogram shows how much time the signal spends
at each voltage level, and is useful for visualising RMS
noise and noise margins; while a horizontal histogram
shows how fast the signal voltage changes during each
time interval, and shows RMS jitter and timing margins.
Histograms help you to visualise the quality of your signal,
but if you prefer you can also get statistics in numerical
form by using the built-in statistics functions.
這么低的價格是否還有其它費用?
There are no hidden extra costs. When you buy a PicoScope 9201A/9211A, you get a complete system: the front-end hardware to plug into your USB port, a mains power adapter, and Windows-based software for your PC. You just provide the computer. You also get valuable extra services: free, time-unlimited support from our technical specialists, and free software updates for as long as we continue to support the product. Of course, every lab needs more than just a scope. You will need cables, connectors, and possibly coaxial splitters and attenuators, but these are all application-specific and you are likely to have them on your shelf anyway. To keep costs down, the PicoScope 9201A/9211A kit does not include probes, which are not needed if you have a 50-ohm signal source.
