Increasing Sweep Speed; To Use Swept List Mode - Agilent Technologies 8753ET User Manual

Increasing Sweep Speed

You can increase the analyzer sweep speed by avoiding the use of some features that
require computational time for implementation and updating, such as bandwidth marker
tracking.
You can also increase the sweep speed by making adjustments to the measurement
settings. The following suggestions for increasing sweep speed are general rules that you
should experiment with:
• use swept list mode
• decrease the frequency span
• set the auto sweep time mode
• widen the system bandwidth
• reduce the averaging factor
• reduce the number of measurement points
• set the sweep type
• use chop sweep mode
• use external calibration
• use fast 2-port calibration mode

To Use Swept List Mode

When using a list frequency sweep, choosing swept list mode can increase throughput by
up to 6 times over stepped list mode. This mode takes data while sweeping through each
list segment. In addition, this mode expands the list table to include test port power and IF
bandwidth. Selectable IF bandwidths can increase the throughput of the measurement by
allowing the user to specify narrow bandwidths only where needed.
• For in-depth information on swept list mode, refer to

2. The frequency segments can be defined in any of the following terms:
• start/stop/number of points/power/IFBW
• start/stop/step/power/IFBW
• center/span/number of points/power/IFBW
• center/span/step/power/IFBW
