Measuring Input Signal Levels and Signal Strength
Minimum, maximum, and peak-to-peak levels of the input signal are indicated on
the bottom of the counter’s main measurement display area and an example is
included in Figure 4-4. These characteristics of the peak-to-peak signal can also
be measured with the commands:
INPut[{1|2}]:LEVel:MINimum? (minimum value of p-p signal)
INPut[{1|2}]:LEVel:MAXimum? (maximum value of p-p signal)
INPut[{1|2}]:LEVel:PTPeak? (p-p amplitude)
The minimum and maximum values include any DC levels (offsets) present with
the signals. The counter’s input impedance also affects the amplitude at the input.
Channel 3 signal strength
The relative signal strength on channel 3 Option 106 or 115 (6 GHz or 15 GHz
microwave input) is displayed on the counter and can also be measured with the
command:
INPut3:STRength?
