N1913A/14A EPM Series Power Meters Performance Characteristics (continued)
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 from 1% to 150%, in 0.1% increments.
Frequency Entered frequency range is used to interpolate the calibration factors table. Frequency range from 1 kHz
to 999.9 GHz. Also settable in 1 kHz steps.
Cal factor Sets the calibration factor for the meter. Range: 1% to 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 dB to +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 Watts 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% to 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 dBm to +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.
