2 General Power Meter Functions
72 N1911A/1912A P-Series Power Meters User’s Guide
Setting External Trigger for Normal and Average Power
Measurement
There are two modes featured in peak and average power measurement
• Power sweep mode
• Frequency sweep mode
These modes are used to eliminate the need for lengthy test routines,
while increasing measurement throughput by reducing overhead of
communication with the controller. The sweep feature allows you to make
power measurement by quickly stepping through a series of frequencies or
power levels. Configuration shown in Figure 2- 58 illustrates the triggering
connection required to synchronize power meter measurement to the
power source settings.
Table 2- 5 below shows the power and frequency sweep mode compatibility
in normal and average mode. Measurement averaging and trace display
will be turned OFF in E- Series E9320 and P- Series N1920 power sensors
while performing power or frequency sweep during normal mode.
Table 2 - 5 Power and frequency sweep mode compatibility table
* Average only mode measurement is calculated based on peak measurement operation
for the P-Series N1920 power sensor.
