4.4.3.2.8 Set Ref
Used to make relative measurements such as attenuator measurement. When this key is pressed, the system is
instructed to make a relative measurement, so the range1 initial power is not obtained from the power meter. The
reference power is that power measured by PSA while the key is pressed.
NOTE If Set Ref key was previously pressed, the Amplitude/Y Scale menu is not available.

Applies only to instruments with Option Driver part number E444060253 and firmware release less than
A.11.00. Press ,
System More
Adds a 5 minute delay when switching from Range 2 to Range 3. Range 3 turns on the internal preamplifier and
this delay is necessary to allow the preamplifier to settle. When performing the Ranging Calibration, ensure that
the Range 3 Switch Delay is ON for both the Ranging Calibration and the TRFL measurement routines, since
you may perform the Ranging Calibration as a separate routine. However, you can take advantage of the fact that
the Ranging Calibration will be triggered automatically (if the Range Switching is set to AUTO) as part of the
TRFL measurement routine.
