Select Reference Oscillator
Selects the signal from the external reference input as timebase instead of the in
-
ternal timebase oscillator. If the parameter is set to the default value AUTO,
external reference will be used, if present.
Returned format: <INT|EXT|AUTO>¿
*RST condition: AUTO
Complies with standards: SCPI 1991.0, confirmed.

8 «ON|OFF»
Automatic Recognition of Basic Frequency for TIE Measurement
If AUTO is ON, a check measurement is made at the start of the block to deter-
mine if the frequency of the input signal, rounded to 4 significant digits, is listed for
automatic recognition, for instance:
4, 8, 15.75, 64 kHz or
1.544, 2.048, 5, 10, 27, 34, 45, 52 MHz
If the command is successful, the found value will be stored and can be recalled
with a query command. Subsequent TIE measurements will use this value until it is
changed by sending this command once more or by sending the setting command
:TIError:FREQuency 8 <Numeric value>, which will deliberately fix the fre
-
quency.
Returned format: 1|0¿
*RST condition: OFF¿
