Reference Oscillator Configuration
53210A measurements are based on a reference oscillator - also referred to as an
internal/external clock or time base. A valid reference oscillator signal must be
present for measurements to occur.
The following information applies to the counter's standard temperature
compensated crystal oscillator (TCXO) and Option 010 Ultra High-Stability
oven-controlled crystal oscillator (OCXO) references.
Reference Oscillator Source
The reference oscillator (time base) is either the counter's internal oscillator or the
internal oscillator tuned to an external reference. The source commands are:
[SENSe:]ROSCillator:SOURce {INTernal|EXTernal}
[SENSe:]ROSCillator:SOURce?
[SENSe:]ROSCillator:SOURce:AUTO {OFF|ON}
[SENSe:]ROSCillator:SOURce:AUTO?
