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)
Frequency Entered frequency range is used to interpolate the calibration factors table. Frequency range from
1 kHz to 999.9 GHz
Bridge resistance type Setting the bridge resistance, user-selectable Rmeasure (factory set) or Ruser (measured by user)
Cal factor Sets the cal factor versus frequency for the calibration factor for power sensor. Range: 1.00% to
150.00%, in 0.01% increments. Cal factor can be set from either CF table or single entry CF
Relative Displays all successive measurements relative to the last displayed value
Offset Allows power measurements to be offset by –100 to +100 dB, settable in 0.001dB increments, to
compensate for external loss or gain. Offset table can be set from either CF table or single entry
CF
Save/recall Store up to 10 instrument states via the save/recall menu
Measurement averaging Selectable from 4 to 128
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
Limits High and low limits can be set in the range –150.000 to +230.000 dBm, in 0.001 dBm increments
Preset default values dBm mode, relative off, power reference off, duty cycle off, offset off, frequency 50 MHz,
measurement averaging 16, free run
Display Color display with selectable single and split screen formats are available. User selectable on
digital measurement type or analog scale presentation
1 mW (0 dBm) power reference
Accuracy (for two years)
SWR
1.0 mW (0.0 dBm), 50 MHz from type N (f) connector on the front panel, for power meter/sensor
function check.
