Anritsu ML2437A - Offset

Front Panel Operation Sensor Menu
ML2437A/38A OM/PM PN: 10585-00001 Rev. P 5-11
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:
VALUE [OFFFIX OFFVAL]
Enter the offset value (dB) when Offset TYPE is set to Fixed. Valid range is –99.99 to
+99.99.
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 frequency is used to calculate the
offset from the table. If the frequency 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, interpolation is
used to calculate the correct offset.
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 process.
Note
If the frequency is greater than the maximum frequency in the table, the offset
value from the maximum table frequency is used. If the frequency is less than the
minimum frequency in the table, the offset from the minimum table frequency is
used.
