Use Standard Oscilloscope Probes with BitScope Micro!

MP01 makes it possible to use standard oscilloscope probes with BitScope Micro.

Passive probes that have 1:1, 10:1, 100:1 or other attenuation ratios can be used. It also supports active differential probes, current probes and most other types of probe which are BNC terminated and designed for use with standard scope inputs.

This is possible because despite its tiny size and appearance, BitScope Micro has electrically compatible analog inputs with 1MΩ/20pF impedance so compensation circuits in standard probes will work the same with BitScope Micro and MP01.

If you need to connect only one probe or you want an in-line solution we recommend Tom Thumb (MP02) instead.

Well connected with Assignable Inputs & Outputs

Extending the BitScope Micro Diagnostic Port, MP01 offers even more flexible signal routing options.

In addition to the BNC inputs, the analog channels also appear on the header.

Analog (or logic) signals connected via either set of analog inputs are routed to BitScope Micro's logic channels 6 and 7 via its built-in comparators.

This means it's possible to capture up to 8 logic channels at once where two channels can be set to switch at an adjustable level which is ideal for unusual logic families or specialised signal standards (e.g. bipolar or negative voltage logic).

Flexible Signal Routing

Colour coded shorting plugs are supplied which allow up to two unused inputs to be shorted for ground reference. In the case of the analog inputs it also prevents noise or crosstalk from unconnected inputs. The shorting plugs may also be used to route the waveform generator output to the CHB BNC socket and the built-in clock generator to CHA.

The keycard shows how this is done.

Using the shorting plugs the CHA BNC connector can be connected to ground, CLK/L5 or L3 and CHB BNC connector connected to ground, AWG/L4 or L0.

In addition to grounding, waveform and clock outputs, connecting either analog input to an adjacent logic channel reduces the input impedance of the analog input from 1MΩ to 100kΩ which in can be very handy if the lower input impedance is required.

The fully programmable signal control provided by the BitScope Micro Diagnostic Port is available via MP01. For example the four logic channels can be set as active low pull-downs to configure a connected circuit for up to 16 states of operation.

Supports Wide Range of Voltages

This table enumerates full scale voltage ranges available with MP01 when used with BitScope Micro and a 1:1, 10:1 and 100:1 probe.

It shows the maximum peak-to-peak signal that can be captured at full resolution with (8 bits in normal mode and up to 12 bits in macro mode).

With BitScope DSO this is simply a matter of right-clicking the probe scale widget and choosing the right scale. In the example shown here, a probe scaling of 2:1 has already been chosen but the prescaler (1:5) is about to be selected instead.

Many scaling options are available to support the wide range of oscilloscope probes available because all of them can be used with BitScope Micro and MP01.
