with no power applied to the power sensor. Refer to "Zeroing and
Calibrating the Power Meter", on page 2-7 for further information.
• Zero B
Press this softkey to adjust channel B's internal circuitry for a

Refer to "Zeroing and Calibrating the Power Meter", on page 2-7
for further information.
•
Zero Both
Press this softkey to adjust both channel A's and channel B's
internal circuitry for a zero power reading with no power supplied
to the power sensor. Refer to "Zeroing and Calibrating the Power

• Cal
Press this softkey to access a menu which allows you to calibrate
the power meter. Calibration sets the gain of the power meter
using a 50 MHz oscillator as a traceable power reference.
Cal A
Press this softkey to calibrate channel A with the connected
power sensor. The POWER REF output is used as the signal
source for calibration and is automatically switched on during
this procedure.
A Ref CF
Press this softkey to enter a reference calibration factor for
channel A. A value in the range of 1% to 150% can be entered.
