RESET
Sweep average reset. If the graph sweep averaging state is ON,
this key resets the data points and restarts the sweep to sweep
mode.
CURSOR
[GRSWR] Between cursor averaging ON or OFF. When ON, a digital readout
of the average power between the two cursors is displayed in the
readout area of the PROFILE display.
Offset Allows an offset, in dB, to be applied to sensor data for the selected sensor.
SENSOR Model ML2438A (dual channel) only. Used to select the sensor to
be configured. Toggles between Channel A and Channel B for all
submenu functions.
TYPE
[OFFTYP] Selects the type of offset to be applied:
Off
No offset applied.
Fixed
A fixed dB offset VALUE is applied to the sensor data.
Table
The tables are a set of frequency-against-dB offsets. The offset
value used from the table depends on the setting of the frequency
correction source. If the source is FREQUENCY, the entered fre-
quency is used to calculate the offset from the table. If the fre-
quency correction source is V/GHz, the frequency value calculated
from the supplied ramp input is used to calculate the offset from the
table.
If the frequency does not match any frequency in the table, interpo-
lation is used to calculate the correct offset.
NOTE
If the frequency is greater than the maximum frequency in
the table, the offset value from the maximum table fre-
quency is used. If the frequency is less than the minimum
frequency in the table, the offset from the minimum table
frequency is used.
VALUE
[OFFFIX
OFFVAL] Enter the offset value (dB) when Offset TYPE is set to Fixed. Valid
range is –99.99 to +99.99.

NOTE
Use Fixed or Table to
compensate for a fixed
attenuator on a sensor
for measuring higher
power levels. A better
method is to apply a
Fixed cal factor in the
User tables as this is
then taken into account
in the Zero/Cal pro-
cess.
