8 Frequency Scan Measurement
Meas Setup
Dependencies This key is grayed out when the Step Control is set to “Step Size & Dwell Time”. If the grayed out key
is pressed, an advisory message is generated. If the equivalent SCPI command is sent, this same
message is generated as part of a “–221, Settings conflict; Function not available while running
multirange scan” warning.
This key is grayed out during multi range scanning. If the grayed out key is pressed, an advisory
message is generated. If the equivalent SCPI command is sent, this same message is generated as
part of a “–221, Settings conflict; Function not available while running multirange scan” warning.
This key is grayed out during final measurement. If the grayed out key is pressed, an advisory
message is generated. If the equivalent SCPI command is sent, this same message is generated as
part of a “–221, Settings conflict” warning.
This key is grayed out during a Time Domain Scan. If the grayed out key is pressed, an advisory
message is generated. If the equivalent SCPI command is sent, this same message is generated as
part of a “–221, Settings conflict; Function not available with time domain scan type” warning.
When in the Discrete (Stepped) and Time Domain Scan, there is no Auto setting for the scan time.
The Auto/Man line on the Dwell Time softkey disappears in this case, and if the SCPI command.
[:SENSe]:SCAN[1]|2|3|4|5|6|7|8|9|10:TIME:AUTO ON is sent, it generates an error.
Couplings When you change the value of the scan time, the dwell time of the selected range will be changed
accordingly, based on the calculation dwell time = scan time / (scan points–1).
The Scan Time Auto selection is only available when in Smooth Scan. In Scan Time Auto, the scan
time will be set according to the SA- Normal sweep time rules for the active non EMI trace detector.
However, the EMI trace detector will have different sweep time rules.
If the calculated auto scan time is greater than the maximum scan time, a warning message “Setting
Alert; Sweep Rate Unavailable” is displayed, and the scan time will be set to the maximum value; if
the scan time is set to a value less than the calculated auto sweep time, a warning message “Meas
Uncal” is displayed.
Auto Scan Time and Auto Dwell Time are always coupled.
