Key Description
Press ZERO to measure the offset voltages in the signal path and zero the V3500A. This allows a
more accurate measurement at low power levels. The V3500A RF input may be left disconnected
when it is zeroed, or it may be connected to other hardware, but make sure that no signals are
present on the RF input as this results in inaccurate readings. For example, if the V3500A is
connected to a signal generator, turn off the signal generator's output before pressing the ZERO
keypad. When the V3500A is zeroed, the display will show "Zeroing.....". The entire operation will
take approximately 30 seconds.
Press FREQUENCY to set the V3500A to the frequency of the input signal. There are two keypads for
adjusting the frequency. The left arrow key decrements the present frequency in 10 MHz steps.
Likewise, the right arrow key increments the present frequency in 10 MHz steps. The present
frequency is displayed on the second line of the display. Pressing and holding one of the frequency
keys down will change the frequency setting rapidly.
Press ON/OFF to turn on or turn off the V3500A.
