The E-Series E9320 Power
Sensors in Detail
The E-series E9320 power sensors have two frequency
ranges. The E9325A, E9326A, and E9327A have a frequency
range of 50 MHz to 18 GHz while the 50 MHz to 6 GHz range of
the E9321A, E9322A, and E9323A covers most wireless
communication applications.
The sensors have two independent measurement paths as
shown in Figure 1.

Use the default normal path for continuously sampled
measurements of modulated signals and time gated
measurements. For each frequency range there is a choice of
sensors with three video (modulation) bandwidths.
