V3500A User's Guide
In normal operation speed, the V3500A will complete a
power measurement in about 1 second (± 0.5 second
depending on the power level of the input signal). Lower
level signals take longer to measure than higher level signals.
This is due to the fact that more filtering is required to get
a good signal- to- noise ratio when measuring low- level
signals.
If faster measurements are required, set the V3500A to
high- speed mode. In this mode (for measurements greater
than –30 dBm) the V3500A can make approximately
23 measurements per second.
In most cases, the normal measurement speed is the best
choice. Measurement data filtering is greatly reduced in
high- speed mode, resulting in significantly higher
measurement noise than in normal mode.
The instrument returns to the default "Meas mode" setting of <Norm>
when the instrument is turned off.
1 Press MENU to enter menu mode.
2 Scroll using the down menu arrow keypad until "Meas
mode" menu is displayed.
3 Press the left or right menu arrow keypad to select the
desired measurement speed mode. There are two available
options:
• <Norm>: Selects normal measurement speed mode
