Frequency and Amplitude
The RF output signal is not changed when you press this key.
Units
When you press
REF SET for frequency, values can be entered in MHz or kHz. For
amplitude, values can be entered in any of the amplitude units provided, but they are
displayed in dB only.
4. REF ON/OFF
Press REF ON/OFF to turn off the reference mode if it is on, or to turn on the reference mode
without changing the reference value.
When you turn on the reference mode, the displayed value indicates the offset between the
reference value and the current RF output setting.
The RF output signal is not changed when you press this key.
Output Power Trouble? If the RF output power seems too low, look for ∆ in the display
between the power level value and the dB indicator. The ∆ tells
you that reference mode is turned on. The displayed value is not
the output power level; it is the offset between the reference value
and the output power. To exit the reference mode, press
REF ON/OFF. You can then reset the output power to the desired
level.
