Optimizing Measurement Results
Increasing Sweep Speed
• Continuous: In this mode the analyzer will switch between the test ports on every
sweep. Although this type of test set switching provides the greatest measurement
accuracy, it requires a reverse sweep for every forward sweep.
NOTE Analyzers configured with Option 007 or Option 085 use a mechanical switch
and are not allowed to switch between test ports on every sweep in
Continuous mode. A tsh indicator appears on the display instead.
• Number of Sweeps: In this mode there is an initial cycling between the test ports and
then the measurement stays on the active port for a user-defined number of sweeps.
After the specified number of sweeps have been executed, the analyzer switches
between the test ports and begins the cycle again. This type of test set switching can
provide improved measurement accuracy over the hold mode and faster measurement
speeds than continuous mode.
NOTE Fast 2-Port Calibration Accuracy
For most devices, the fast 2-Port Calibration method is nearly as accurate as
the full 2-Port Calibration method.
