Enabled
Same as Enabled under the Bandwidth index tab. See"Enabled" on page 1682.
Start Freq
Same as the Start Freq column under the Bandwidth index tab. See"Start Freq" on
page 1683.
Stop Freq
Same as the Stop Freq column under the Bandwidth index tab. See"Stop Freq" on
page 1684.
Center Frequency
Sets the center frequency of the instrument. This parameter can send up to 20
values. The location where the center frequency occurs in the list sent to the
measurement corresponds to the range the value is associated with.
When sending the remote command, missing values are not permitted. If you want
to change values 2 and 6 you must send all values up to 6. Subsequent values will
remain as they were.
The query always returns 20 values.
