Verifying Probe Input Resistance; Verifying Probe Rise Time - Agilent Technologies 1155A User Manual

Verifying probe input resistance

Specification: 1.0 MΩ ±2%
Equipment Required
Equipment
Digital Multimeter
(DMM)
Connect the DMM probes between the probe tip (ChA) and the ground
1
at the tip of the probe.
Set up the DMM to measure resistance.
2
Record resistance and repeat steps 1 through 3 for ChB.
3
Enter these value in the Test Card.

C A U T I O N Allow the probe to warm up for at least 15 minutes prior to starting the
calibration tests. Failure to allow the probe to warm up may cause the probe
to fail tests.
