[SENSe[<chan>]]:ROSCillator:SOURce

Using MINimum or MAXimum to specify this frequency is not recommended unless the external reference frequency is 20 kHz (MINimum) or 20 MHz (MAXimum). In order for the digitizer processor to produce the intended sample rates, the exact frequency value must be specified.

[SENSe[<chan>]]:ROSCillator:SOURce <source> selects the reference oscillator

source. The available sources are:

CLK10: The VXIbus CLK10 (10 MHz) line.

ECLTrg0: The VXIbus ECLTRG0 line.

ECLTrg1: The VXIbus ECLTRG1 line.

EXTernal2: The HP E1429’s front panel "Ext 2" BNC.

INTernal: The internal 20 MHz oscillator.
