Key Features and Functions

The N1921A P-Series Wideband Power Sensor, 50 MHz - 18 GHz sensor is the first to provide internal zero and calibration, by integrating a DC reference source and switching circuits into the power sensor. This feature eliminates the multiple connections associated with using an external calibration source, thus minimizing connector wear, test-time and measurement uncertainty. The N1921A is used with the N1912A P-Series Dual Channel Power Meter.

  • Zero and calibrate while connected to the DUT
  • -35 dBm to +20 dBm wide dynamic range for peak power measurements
  • Calibration factors, linearity, temperature and bandwidth correction data stored in EEPROM
  • Precision Type-N connector as standard
  • Sensor cable fixed to sensor. Available cable lengths are 1.5m (5ft), 3m (10ft) and 10m (31ft)
Frequency range 50 MHz to 18 GHz
Average power measurement ≤ ± 0.2 dB or ± 4.5 %
Dynamic range –35 dBm to +20 dBm (> 500 MHz)
–30 dBm to +20 dBm (50 MHz to 500 MHz)
Damage level +23 dBm (average power);
+30 dBm (< 1 μs duration) (peak power)
Connector type Type N (m)
Maximum SWR 1.2
Frequency band 4.5 %
Dimensions 135 mm x 40 mm x 27 mm
(5.3 in x 1.6 in x 1.1 in)
