Frequency range: DC...120 GHz, sensor dependent

Power range: –70...+44 dBm (100 pW...25 W), sensor dependent

Single sensor dynamic range: 90 dB max. (Keysight E series power sensors)

50 dB max. (Keysight 8480 series power sensors)

55 dB max. (Keysight N8480 series power sensors)

80 dB max. (Keysight E/V/W8486A waveguide power sensors

80 dB max. (Keysight U2000 series USB power sensors)

55 dB max. (Keysight U8480A series USB power sensors)

96 dB max. (Keysight U2040x series, except U2049X series and in average mode only)

Display units: Absolute: Watt or dBm; relative: Percent or dB

Display resolution: Selectable resolution of 1.0, 0.1, 0.01 and 0.001 dB in logarithmic mode, or 1, 2, 3 and 4 significant digits in linear mode

Default resolution: 0.01 dB in logarithmic mode or three digits in linear mode

Measurement speed: Using remote interface (over the GPIB, USB or LAN), three measurement speed modes are available as shown, along with the typical maximum measurement speed for each mode:

With N1913B power meter: Normal 20 readings/s, x2 40 readings/s, fast: 400 readings/s, for Keysight E series power sensors only.

Fast mode is for Keysight E-Series power sensors only.

Maximum measurement speed is obtained using binary output in free run trigger mode.

Power meter functions: 

Accessed by key entry:Either hard keys, or soft key menu, and programmable.

Zero: Zeros the meter (power reference calibrator is switched off during zeroing).

Cal: Calibrates the meter using internal (power reference calibrator) or external source. Reference cal factor settable 1...150%, in 0.1% increments.

Frequency: Entered frequency range is used to interpolate the calibration factors table. Frequency range 1 kHz...999.9 GHz. Also settable in 1 kHz steps.

Cal factor: Sets the calibration factor for the meter. Range 1...150%, in 0.1% increments.

Relative: Displays all successive measurements relative to the last displayed value.

Offset: Allows power measurements to be offset by –100...+100 dB, settable in 0.001 dB increments, to compensate for external loss or gain.

Save/recall: Store up to 10 instrument states via the save/recall menu.

dBm/W: Selectable units of either Watt or dBm in absolute power; or percent or dB for relative measurements.

Filter (averaging): Selectable from 1 to 1024. Auto-averaging provides automatic noise compensation.

Duty cycle: Duty cycle values between 0.001...99.999%, in 0.001% increments, can be entered to display a peak power representation of measured power. The following equation is used to calculate the displayed peak power value: peak power = measured power/duty cycle.

Sensor cal tables: Selects cal factor versus frequency tables corresponding to specified sensors.

Limits: High and low limits can be set in the range –150.000...+230.000 dBm, in 0.001 dBm increments.

Preset default values: dBm mode, rel off, power reference off, duty cycle off, offset off, frequency 50 MHz, AUTO average, free run, AUTO range (for E series sensors and N8480 series).

Display: Color display with selectable single and split screen formats are available. A quasi-analog display is available for peaking measurements. The dual channel power meter can simultaneously display any two configurations of A, B, A/B, B/A, A-B, B-A and relative. With the optional USB ports, additional dual channel (C & D), adds up to total 4-channels measurement display.

Interfaces: USB 2.0, Ethernet/LAN (LXI-C), GPIB, SCPI compatible, optional VGA, optional USB-Port for additional sensor connection
