Performance Verification for N2830A-Series Probes

Bandwidth Performance Verification

This procedure documents the bandwidth performance of the N2832A InfiniiMax
III+ probe amplifier with the N2836A solder-in probe head.
The recommended test interval is one year/2000 hours.

covers at least a 50 MHz to 13 GHz range. The VNA must have the following
capability:
• Ability to use a Touchstone file to de-embed at a port.
• A bias port for port 1 of the VNA. That is it must have an internal bias T's and
a BNC port that allows bias to be applied to port 1.
