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 repre-

sentation 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.
