Peak/Average Power Sensor (50 MHz – 6 GHz; 300 kHz Video Bandwidth)
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.

Measurement ranges
The E9320 power sensors have two measurement ranges (lower and upper).
| E9321A/E9325A | E9322A/E9326A | E9323A/E9327A | ||||
| Normal | Average only | Normal | Average only | Normal | Average only | |
| Lower range (min. power) | -50 dBm | -65 dBm | -45 dBm | -60 dBm | -40 dBm | -60 dBm |
| Lower range (max. power) | +0.5 dBm | -17.5 dBm¹ | -5 dBm | -13.5 dBm² | -5 dBm | -10.5 dBm² |
| Lower to upper auto range point | +0.5 dBm | -17.5 dBm¹ | -5 dBm | -13.5 dBm² | -5 dBm | -10.5 dBm² |
Upper to lower auto range point | -9.5 dBm | -18.5 dBm | -15 dBm | -14.5 dBm | -15 dBm | -11.5 dBm |
| Upper range (min. power) | -35 dBm | -50 dBm | -35 dBm | -45 dBm | -30 dBm | -35 dBm |
| Upper range (max. power) | +20 dBm | +20 dBm¹ | +20 dBm | +20 dBm² | +20 dBm | +20 dBm² |
¹ For average power measurements, free run acquisition
² Applies to CW and constant amplitude signals only above -20 dBm
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 videos (modulation) bandwidths.
Note: however, that the sensors with the widest bandwidth have the smallest dynamic range (in normal mode). If the dynamic range is an important factor, use the sensor model with just enough video bandwidth for the measurement you want to make.
The average-only path is suitable for average power measurements of Continuous Wave (CW) and constant amplitude signals between -65 dBm (sensor dependent) and +20 dBm. The average-only path can also be used to measure the true average power of any complex modulated signal below -20 dBm.
Calibration factors, linearity, temperature, and bandwidth compensation data are stored in the sensor EEPROM during the manufacturing process. All the compensation data is downloaded to the EPM-P Series power meter at power-on or when the sensor is connected. You only need to enter the frequency of the RF signal you are measuring to achieve a high degree of accuracy.
