The Probe Check softkey guides you through the process of compensating
passive probes (such as the N2862A/B, N2863A/B, N2889A, N2890A,
10073C, 10074C, or 1165A probes).

To specify the channel units
1 Press the probe's associated channel key.
2 In the Channel Menu, press Probe .
3
In the Channel Probe Menu, press
Units
; then, select:
•
Volts
— for a voltage probe.
•
Amps
— for a current probe.
Channel sensitivity, trigger level, measurement results, and math functions
will reflect the measurement units you have selected.
To specify the probe attenuation
The probe attenuation factor must be set properly for accurate
measurement results.
To set the probe attenuation factor:
1 Press the channel key.
2 Press the Probe softkey until you have selected how you want to specify
the attenuation factor, choosing either
Ratio
or
Decibels
.
3 Turn the Entry knob to set the attenuation factor for the connected
probe.
When measuring voltage values, the attenuation factor can be set from
0.1:1 to 1000:1 in a 1- 2- 5 sequence.
When measuring current values with a current probe, the attenuation
factor can be set from 10 V/A to 0.001 V/A.
When specifying the attenuation factor in decibels, you can select values
from - 20 dB to 60 dB.
