N7026A Probe
Performance Verification for N7026A
Use the following procedure to test the warranted Accuracy specifications for the N7026A
probe (as listed on
page 10
). The recommended test interval to warrant performance of this
probe is once a year. However, you can also test the probe’s performance as and when
required using the recommended test equipment and by following the procedure
documented in this chapter.
Procedure
1
Turn on the oscilloscope and then connect the N7026A probe to the oscilloscope.
2
Set A/div to
10mA/div
.
3
On an Infiniium oscilloscope, choose
Setup > Probe Configuration....
to access the
Probe
Configuration
dialog box and then record the
Attenuation
scale factor. On an InfiniiVision
oscilloscope, use th
e
Probe
softkey to record the attenuation scale factor of the probe.
