6 RLC Swept SA Measurement Front-Panel & SCPI Reference
Input/Output
The values sent in the command will totally replace all existing correction points in the specified
set.
An Ampcor array can contain a maximum of 2000 points.
Remote Command [:SENSe]:CORRection:CSET[1]|2|...6:DATA <freq>, <ampl>, . . .
[:SENSe]:CORRection:CSET[1]|2|...6:DATA?
Example CORR:CSET1:DATA 10000000, –1.0, 20000000, 1.0
This defines two correction points at (10 MHz, –1.0 dB) and (20 MHz, 1.0 dB) for correction set 1.
Preset Empty after Restore Input/Output Defaults. Survives a shutdown or restart of analyzer
application (including a power cycle).
State Saved Saved in instrument state.
Min Freq: 0 Hz
Amptd: –1000 dBm
Max Freq: 1 THz
Amptd: +1000 dBm
Initial S/W Revision A.02.00
Freq Ref In
Specifies the frequency reference as being the internal reference, external reference or sensing the
presence of an external reference.
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.
If Sense is selected, the instrument checks whether a signal is present at the external reference
connector and will automatically switch to the external reference when a signal is detected. When
no signal is present, it automatically switches to the internal reference. No message is generated
as the reference switches between 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 2 in
the Questionable Frequency register will be true and a condition error message is generated.
When lock is regained, Status bit 2 in the Questionable Frequency register will be cleared and the
condition error will be cleared.
