HOLD
[RGH]
Allows the operating range of the selected sensor to be set to the
desired range. Select a Range Hold value of 1 to 5, or Auto. When
in Auto, the range changes to take the best measurement automati-
cally. Auto is the default setting following system preset.
Typical Range Hold values for diode sensors are:
Range 1
above approximately –12 dBm
Range 2
–10 to –27 dBm
Range 3
–25 to –42 dBm
Range 4
–40 to –57 dBm
Range 5
below –55 dBm
SETTLE %
[SENSTL]
Settle % per reading is available when the sensor mode is set to
Default. The settling time allows some control over the tradeoff be-
tween speed and the extent to which a measurement has settled to
its final value. A 1% settling value relates to approximately 0.04 dB,
0.5% relates to 0.02 dB and 0.25% to 0.01 dB. The default value af-
ter a system preset is 0.1%, or about 0.004 dB. Increasing the Set-
tle percent to 1% or more will substantially increase measurement
speed.
Calfactor
Allows entry of the calibration correction factor. The calibration factor compen-
sates for mismatch losses and effective efficiency over the frequency range of the
power sensor.
SENSOR
Model ML2438A (dual channel) only. Select the sensor to be con-
figured. Toggles between Sensor A and Sensor B for all submenu
functions.
SOURCE
[CFSRC
CFVAL]
Three selections are available, Frequency, Manual, and V/GHz.
Frequency
In this mode, correction data is read from the EEPROM in the sen-
sor and applied automatically to the measurement based on the us-
er’s input frequency. The EEPROM correction data value nearest to
the entered frequency is used to calculate the correction applied to
the signal.

this when optimizing
GPIB performance.
NOTE
Frequency or V/GHz are pre-
ferred methods as the sen-
sors have internal linearity
correction which varies with
frequency.
NOTE
The HOLD selection is
not available when
System/Setup/mode is
set to Source Sweep.
In this mode, AUTO
ranging is used.
