The reading now shows the risetime from 10%-90% of the trace amplitude and the voltage at the cursors in relation to the zero icon (-). See Figure 1-21.

Using the 10:1 Probe for High Frequency Measurements.

Fluke 124 is supplied with a model VP40 10:1 Probe. Use

Turn off the cursors.of this Probe is recommended when you measure high frequency signals in circuits with a high impedance. The loading of the circuit by a 10:1 Probe is much lower than that of a 1:1 Shielded Test Lead.

The following aspects must be observed when using a 10:1 Probe:

Probe Attenuation.

The Probe attenuates the signal 10 times. Proceed as follows to adapt the Test Tool’s voltage readout to this attenuation. The example below is for a Probe connected to input B:
