FREQ:MIDS?
Notes The Max values are depending on Hardware Options (503, 507, 508, 513, 526)
Dependencies
TheFrequency can be limited by Start or Stop Freq limits, if the Span is so large that Start or Stop
reaches their limit.
Preset 515 MHz
State Saved Saved in instrument state.
Min Depends on the instrument minimum frequency and 10 Hz minimum span. If the knob or step keys
are being used, it depends on the value of the other three interdependent parameters.
Max Depends on the instrument maximum frequency – 10 Hz minimum span. If the knob or step keys are
being used, it depends on the value of the stop frequency

Dependencies By direct entry:
You cannot set the Start frequency > the Stop frequency. You cannot set the Start frequency = the
Stop frequency. You cannot select zero span by setting Start = Stop. You cannot set the Start
Frequency to a value that would create a span of less than 10 Hz. If you try to do any of these, the
Stop Frequency will change to maintain a minimum value of 10 Hz for the difference between Start
