Freq Ref In
Specifies the frequency reference as being the internal reference at the rear panel input labeled EXT REF
IN, a 1 pulse per second signal at the EXT REF IN input,, external reference or sensing the presence of a
signal at the EXT REF IN input.
When the frequency reference is set to internal, the internal 10 MHz reference is used even if an external
reference is connected.
When the frequency reference is set to external, the instrument will use the external reference. However, if
there is no external signal present, or it is not within the proper amplitude range, a condition error message
is generated. When the external signal becomes valid, the error is cleared.
When the frequency reference is set to Pulse, the instrument expects a 1 pulse per second signal at the
EXT REF IN input. The instrument uses this signal to adjust the frequency of the internal reference.
If Sense is selected, the instrument checks whether a signal is present at the external reference connector.
If it senses a signal within 5 ppm of the External Ref Freq (as set on the External Ref Freq softkey), it will
automatically switch to the external reference. If it senses a 1 pulse per second signal, it enters Pulse
mode, wherein the signal is used to adjust the internal reference. When no signal is present, it
automatically switches to the internal reference. No message is generated as the reference switches
between pulse, external and internal. The monitoring of the external reference occurs approximately on 1
millisecond intervals, and never occurs in the middle of a measurement acquisition, only at the end of the
measurement (end of the request).
If for any reason the instrument’s frequency reference is not able to obtain lock, Status bit 1 in the
Questionable Frequency register will be true and a condition error message is generated. When lock is
regained, Status bit 1 in the Questionable Frequency register will be cleared and the condition error will be
cleared.
If an external frequency reference is being used, you must enter the frequency of the external reference if it
is not exactly 10 MHz. The External Ref Freq key is provided for this purpose.
NOTE:
A common frequency reference module serves all instrument instances, but only one instance of the
software application can change the reference input type (INT or EXT or SENSE). The software application
allowed to change the reference input is called the controlling instance; by default, the left most
instrument instance is the controlling instance. This can be changed in the config file
“E66XXModules.config” located under the folder E:\Agilent\Instrument. For the non-controlling instance
