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 2-43 illustrates the triggering connection required to synchronize
power meter measurement to the power source settings.
Table 2-4 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 2-4 Power and frequency sweep mode compatibility table
Sensor Normal Mode Average Mode
848x — Yes
E441x — Yes
E930x — Yes
E932x Yes Yes
N848x — Yes
N192x Yes

[a] Average only mode measurement is calculated based on peak measurement operation for the P-Series N1920
power sensor.
Auto CAL will be temporary disabled in P-Series N1920 power sensors during
power or frequency sweep.
