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.
