Stop Freq
Sets the frequency at the right side of the graticule. While adjusting the stop Frequency, the start
frequency is held constant, which means that both the center frequency and span will change.
Stop Freq also sets the frequency entry mode to Start or Stop. In Start or Stop mode, the start
frequency and stop frequency values are displayed below the graticule, and the default active
function in the Frequency menu is Start Freq.
Key Path FREQ Channel

Example FREQ:STOP 220 MHz
FREQ:STOP?
Notes Preset and Max values are dependent on Hardware Options (5xx)
Dependencies By direct entry:
You cannot set the Stop frequency < Start frequency. You cannot set Start frequency = Stop
frequency. You cannot select zero span by setting Start = Stop. You cannot set Stop Frequency
to a value that would create a span of less than 10 Hz. If you try to do any of these, Start
Frequency will change to maintain a minimum value of 10 Hz for the difference between Start
and Stop.
With the knob or step keys:
Cannot decrement Stop Freq to a value less than Start Freq + 10 Hz. If already in zero span,
cannot decrement at all, and the first increment will be forced to at least 10 Hz.
The Stop Frequency can be limited by Span limits, if the Start Frequency is above its preset
value.
If the electronic/soft attenuator is enabled, any attempt to set the Stop Frequency >3.6 GHz fails
and results in an advisory message. If the equivalent SCPI command is sent, this same message
is generated as part of a “–221, Settings conflict” warning.
If Source Mode is set to Tracking, and the Max or Min Stop Freq is therefore limited by the limits
of the source, a warning message is generated, “Data out of range;clipped to source max/min” if
these limits are exceeded. Note that for an external source, these limits can be affected by the
