You can use the chop sweep mode to make two measurements at the same time. For example,
the analyzer can measure A/R and B/R simultaneously. You can activate the chop mode by
pressing preset) or by the following the sequence below.
For more information, refer to "Alternate and Chop Sweep Modes" in Chapter 6.
Offloading the error correction process to an external PC increases throughput on the network
analyzer. This can be accomplished with remote only commands, Refer to the HP 87533
With the 2-port calibration on, faster measurements may be made by not measuring the reverse
path for every forward sweep. This is controlled by the test set switch command.
When making measurements using full two-port error-correction, the following types of test set
switching can be defined by the user:
Hold: In this mode the analyzer does not switch between the test ports on every sweep. The
n
measurement stays on the active port after an initial cycling between the ports The fastest
measurements can be made by using this type of test set switching. Pressing the m key or
changing to a different S-parameter measurement will cause the test set to switch and cycle
between the ports
Continuous: In this mode the analyzer will switch between the test ports on every sweep.
n
Although this type of test set switching provides the greatest measurement accuracy, it also
takes the longest amount of time.
n
then the measurement stays on the active port for a user-dellned number of sweeps. After
the specified number of sweeps have been executed, the analyzer switches between the
ports and begins the cycle again. This type of test set switching can provide improved
test
measurement accuracy over the hold mode and faster measurement speeds than continuous
mode.
