E-Series Average Power Sensor (9 kHz to 6 GHz)
The E9304A power sensor measures average power over the frequency range 9 kHz to 6 GHz and power range -60 to +20 dBm. This sensor is ideal for very low frequency (VLF) power measurements.
Keysight also offers several options to expand the frequency range to 18 GHz. Please note that the options listed below are sold separately.
- E9304A-H18 – 9 kHz to 18 GHz, -60 to +20 dBm
- E9304A-H19 – 9 kHz to 18 GHz, -50 to +30 dBm
- E9304A-H20 – 9 KHz to 18 GHz, -60 to +20dBm, APC 3.5mm
The Keysight E-Series E9300 is a wide dynamic range, with average power sensors. These sensors are compatible with EPM (N1913A/ 14A, E4418B/ 19B), EPM-P (E4416A/ 17A) and P-series (N1911A/ 12A) power meters.
The chart below provides an overview of the frequency and power ranges covered by each model.
| Frequency Range | Power Range |
| E9300A | 10 MHz to 18 GHz | –60 dBm (1 nW) to +20 dBm (100 mW) |
| E9301A | 10 MHz to 6 GHz | –60 dBm (1 nW) to +20 dBm (100 mW) |
| E9304A | 9 kHz to 6 GHz | –60 dBm (1 nW) to +20 dBm (100 mW) |
| E9300B | 10 MHz to 18 GHz | –30 dBm (1 µW) to +44 dBm (25 W) |
| E9301B | 10 MHz to 6 GHz | –30 dBm (1 µW) to +44 dBm (25 W) |
| E9300H | 10 MHz to 18 GHz | –50 dBm (10 nW) to +30 dBm (1 W) |
| E9301H | 10 MHz to 6 GHz | –50 dBm (10 nW) to +30 dBm (1 W) |
The E-Series E9300 power sensors have two independent measurement paths (high and low power paths).
| " A" Suffix Sensors | " B" Suffix Sensors | " H" Suffix Sensors |
