Band Switch Points - HP 8753E User Manual

3. Then switch to stepped list mode:
If there is no difference between the measurements in either list mode, then use the swept
n
If the memory trace indicates that there is more attenuation in swept list mode, it may be
n
due to IF delay. You can usually remedy this problem by increasing the sweep time.
Note
IF bandwidths of 30 to 10 Hz cause the sweep (or that segment of the sweep)
to be stepped, thus eliminating IF delay.
The hardware of the network analyzer sweeps the frequency range in separate bands, where
switching from band to band takes time. Modify the frequency span to ehminate as many band
switches as possible while maintaining measurement integrity. Refer to the following table to
identify the analyzer's band switch points:
Auto sweep time mode is the default mode (the preset mode). This mode maintains the fastest
sweep speed possible for the current measurement settings.
