AMPTD Y Scale
Dependencies If Normalize is on, Scale Type forced to Log and is grayed out.
Couplings Changing the Scale Type always sets the Y Axis unit to the last unit specified for the current
amplitude scale. In other words, we restore the Y Axis unit setting appropriate per log/lin.

Initial S/W Revision Prior to A.02.00
Presel Center
When this key is pressed, the centering of the preselector filter is adjusted to optimize the
amplitude accuracy at the frequency of the selected marker. If the selected marker is not on when
Presel Center is pressed, the analyzer will turn on the selected marker, perform a peak search, and
then perform centering on the marker’s center frequency. If the selected marker is already on and
between the start and stop frequencies of the analyzer, the analyzer performs the preselector
calibration on that marker’s frequency. If the selected marker is already on, but outside the
frequency range between Start Freq and Stop Freq, the analyzer will first perform a peak search,
and then perform centering on the marker’s center frequency.
The value displayed on the Presel Adjust key will change to reflect the new preselector tuning (see
Presel Adjust
.
A number of considerations should be observed to ensure proper operation. See "Proper
Preselector Operation" on page 531 .
Key Path AMPTD Y Scale
Remote Command [:SENSe]:POWer[:RF]:PCENter
Example POW:PCEN
Notes Note that the rules outlined above under the key description apply for the remote command as
well as the key. The result of the command is dependent on marker position, and so forth. Any
message shown by the key press is also shown in response to the remote command.
Dependencies
•
Grayed out if the microwave preselector is off. )
•
If the selected marker’s frequency is below Band 1, advisory message 0.5001 is generated and
no action is taken.
•
Grayed out if entirely in Band 0.
•
Blank in models that do not include a preselector, such as option 503. If the SCPI is sent in
these instruments, it is accepted without error, and the query always returns 0.
•
Grayed out in the Spectrogram View.
