Keysight Technologies N1921A
50 MHz - 18 GHz P-Series WB Power Sensor (-35 to +20 dBm)
Rent or Lease
The Keysight (Agilent) N1921A P-Series wideband power sensor 50 MHz to 18 GHz, provides internal zero and calibration, by integrating a DC reference source and switching circuits into the power sensor. This feature of the N1921A eliminates the multiple connections associated, by using an external calibration source, thus minimizing connector wear, test-time and measurement uncertainty.
Keysight (Agilent) N1921A - Features and Specifications:
- Wide dynamic range-35 dBm to 20 dBm for peak power measurements
- Precision Type-N connector as standard
- EEPROM stores calibration factors, linearity, temperature and bandwidth correction data
- Zero and calibrate while connected to the device under test (DUT)
- Sensor cable fixed to sensor

Content is AI-generated. Verify critical details with manufacturer-provided resources.
What frequency range does the N1921A wideband power sensor cover?
The N1921A P-Series wideband power sensor operates from 50 MHz to 18 GHz. It features a Type N (m) connector and is designed to work exclusively with P-Series power meters for accurate power measurements across this broad frequency range.
What is the dynamic range of the N1921A power sensor?
The N1921A offers a dynamic range of -35 dBm to +20 dBm for frequencies at or above 500 MHz, and -30 dBm to +20 dBm for frequencies between 50 MHz and 500 MHz. The sensor can handle a maximum average power of +23 dBm and peak power of +30 dBm for pulses less than 1 microsecond duration.
What is the maximum sampling rate for the N1921A when used with P-Series power meters?
When used with P-Series power meters, the N1921A achieves a maximum continuous sampling rate of 100 Msamples per second. This high sampling rate enables capture of fast power transients and supports a video bandwidth of 30 MHz or greater, making it suitable for analyzing pulsed and modulated RF signals.
How accurate is the N1921A for average power measurements?
The N1921A provides average power measurement accuracy of plus or minus 0.2 dB or 4.5% when operating in the 0.5 to 10 GHz frequency range, at power levels from -15 to +20 dBm, with averaging set to 32 in Free Run mode. The accuracy specification includes measurement uncertainty calculated with a 95% confidence level.
What is the rise time specification for the N1921A sensor?
The N1921A has a rise time specification of 13 ns or less for frequencies at or above 500 MHz when the Off video bandwidth setting is selected. This fast rise time enables accurate measurement of pulsed signals, with a recommended minimum pulse width of 50 ns for meaningful and accurate power measurements.
What cable length options are available for the N1921A?
The N1921A is available with three cable length options. The standard version includes a 1.5 meter cable, Option 106 provides a 3.0 meter cable, and Option 107 offers an extended 10 meter cable. The cable length affects the rise time and fall time specifications, with the 10 meter option adding approximately 5 ns to these parameters.
What is the maximum SWR of the N1921A across its frequency range?
The N1921A exhibits excellent input match characteristics with maximum SWR values of 1.2 from 50 MHz to 10 GHz and 1.26 from 10 GHz to 18 GHz. This low SWR minimizes measurement uncertainty due to mismatch, ensuring accurate power measurements across the entire operating frequency range.
Does the N1921A require manual calibration with a power reference?
No, the N1921A features automatic internal calibration and does not require the manual 1 mW power reference calibration needed by legacy E-series and 8480 series sensors. The P-Series sensors perform internal zero and calibration automatically, simplifying setup and improving measurement reliability over time.
