[SENSe:]ROSCillator:TRANge <Range>
Defines the tuning range. The tuning range is only available for the variable external
reference frequency. It determines how far the frequency may deviate from the defined
level in parts per million (10
-6
).
Parameters:
<Range> WIDE | SMALl
The possible values depend on the reference source (see
Table 12-2).
SMALl
With this smaller deviation (+/- 0.5 ppm) a very narrow fixed loop
bandwidth of 0.1 Hz is realized. With this setting the instrument
can synchronize to an external reference signal with a very pre-
cise frequency. Due to the very narrow loop bandwidth, unwan-
ted noise or spurious components on the external reference
input signal are strongly attenuated. Furthermore, the loop
requires about 30 seconds to reach a locked state. During this
locking process, "NO REF" is displayed in the status bar.
WIDE
The larger deviation (+/- 6 ppm) allows the instrument to syn-
chronize to less precise external reference input signals.
Example:
ROSC:TRAN WIDE
Manual operation: See "Tuning Range" on page 702

This command initiates a calibration (self-alignment) routine and queries if calibration
was successful.
