Added value, added power

Fluke CombiScope instruments are a powerful combination of a genuine analogue oscilloscope and a powerful digital oscilloscope in one instrument. There are five models in the

CombiScope B series: three 2-channel models with bandwidths of 60, 100 or 200 MHz, and two 4-channel models with 100 or 200 MHz bandwidth. Instruments now have up to 25 GS/s Sampling Rate for repetitive signals, and 200 MS/s sampling of single-shot events. You'll find 32K deep memory standard on the PM 3394B and PM 3384B models, and 8K on other models. And even there 32K is optional. But we've added even more for your convenience: the Fluke CombiScope B series now comes with a free 7Aath+ firmware package - a powerful capability not normally found in this class of instruments.

Deep memory

The long acquisition memory allows you to scroll through time windows up to 64 screens wide, for convenient viewing of single shot events. Alternatively, you can have a higher time axis resolution across a single screen. This allows you to zoom in and study a particular part of the waveform, e.g. to analyse glitches that might otherwise have escaped your attention.

Fast Sampling Rate

For repetitive signals, the CombiScope PM 3390B and the PM 3394B have a equivalent Sampling Rate of no less than 25 GS/s. Equivalent sampling produces very high time resolution by reconstructing the waveform from different cycles. In this way, you can view repetitive signals at a much higher resolution than would be possible with traditional sampling techniques.

 

The Math+ Package

All CombiScope, instruments can add, subtract and multiply waveforms, and apply digital filtering. The Math+ DSP (Digital Signal Processor) adds advanced mathematical processing of waveforms, as well as a range of other practical features, such as pass/fail testing, amplitude qualified cursors and much more powerful, high-end capabilities.

Waveform processing

Waveform processing as found in the Math+ package results in substantial time saving and additional analytical capabilities. The built-in DSP can run two mathematical operations at any time, on any waveform. Resulting in a screen update-rate that is close to real-time. Using your CombiScope B with Math+ package you can make measurements that would have been impossible with an ordinary scope, such as dissipation analysis, or calculating the momentary power waveform from a digitally filtered input signal.

Fast Fourier Transformation

Fast Fourier Transformation (FFT) converts the conventional amplitude versus time display into the frequency spectrum of the waveform. This information is vital for, e.g., analysing cross talk or measuring distortion. And the integrated FFT capabilities of your CombiScope Math+ package make postprocessing of scope data in a PC obsolete.

Integrate and differentiate

What you measure is not always what you want to know, since many transducers produce an output that is proportional to the change of the input signal. Integrating the output signal of an accelerometer, for example, will produce displacement over time on the oscilloscope screen. Another example is converting the instantaneous power curve {U(t) * I(t)} into the dissipation curve.

Differentiation of input waveforms will reveal the amount of change in the input signal. This can be used, for example, to simulate the effect of AC coupling in electronic circuits.

Multiple single shot mode

The CombiScope B-Series offer a unique multiple single shot mode. Now you can capture a series of single shot recordings of a waveform and store them for later analysis or comparison. This is a most valuable feature, for example to find all malfunctions that occurred during long-term monitoring without you constantly having to watch the screen.

Pass/fail testing

You can test waveforms against pre-defined reference templates, and take go/no-go decisions. You can create the templates on-screen or download them from a PC.

A dedicated output indicates faulty waveforms, which allows the CombiScope to be integrated within an automated test environment. The instrument can also perform a wide range of standard tests, including amplitude peak-to-peak, DC value, RMS value, rise time and frequency

Clever cursors

The Math+ package includes

'amplitude qualified cursors', a handy toolbox to generate customer specified test set-ups. You can now define the 0% and 100% level for both cursors independently Then you have them search for the -50% or + 150% level automatically and determine their position relative to each other or the waveform. In this way you can perform fully automatic testing of even the most complicated waveform parameters, such as diode reverse recovery time.
