Active Measurements —
Displays all frequencies that have been added to the measurement configuration.
Frequencies are listed in MHz. Column headers (from left to right):
Fundamental in MHz
Harmonic (overtone) number (1-5)
Intermod number (-3 to 3, 0 means no IMD)
Frequency in MHz.
Filter width
Clicking on a fundamental in the list will highlight all frequencies for the fundamental.
Note:
Harmonics or IMD frequencies can be clicked on individually.
Note:
Clicking the “<< Remove” button will remove the highlighted frequencies from the list.
Tracking Settings are displayed to the right of the frequency information.
Min/Max Frequency —
Displays the minimum and maximum frequencies the receiver is capable of measuring.
Number of frequency components —
Displays the number of selected fundamentals, harmonics, and
intermods.
Maximum of 12 can be selected with the Standard FPGA selected. (See
.)
Maximum of 6 can be selected with the Time Domain FPGA selected. (See
.)
Number of intermods —
Displays the number of intermods selected.
Maximum of 6 can be selected.
Tracking Settings —
A Fundamental button is active for each frequency fundamental selected. When clicked the
open a dialog box for configuring the settings the receiver will use to measure the selected fundamentals,
harmonics, and intermods.

Voltage Noise Level —
Minimum threshold required for the voltage reading. If the voltage
reading is below this level, the voltage reading will show as 0.
Current Noise Level —
Minimum threshold required for the current reading. If the current
reading is below this level, the reading will show as 0.
Measurement —
used to select how/when the receiver tracks the fundamental frequency.
CW - Continuous measurement, no sync pulse required, receiver tracks the fundamental frequency
during measurement.
Pulse - Sync pulse is used to determine measurement period, receiver only tracks and measures
signals during active sync pulse.
