trace data is weighted exponentially, added to the previous average value and then take the average. In the
exponential average mode, the weight of the new data is larger than that of the old data, which is conducive
to track signals that change slowly. Measured average result will be displayed after the sweeping.
When the repetition average mode is selected, after a specified average time is reached, all the previous
data will be delete and restart the sweeping.
Avg Type: Log-Pwr averaging is to average the logarithmic amplitude values (in dB) of the signal envelope
measured within a signal collection unit, the average detection type will change to video detection. Power
averaging is to average the power of the signal (the square of the amplitude),the average detection type will
change to RMS (power) detection.Voltage averaging is to average the voltage values of the signal envelope
measured in a signal collection unit, the average detection type will changed to voltage detection, The
voltage averaging is still a linear display.
Noise BW: Set the bandwidth of the main channel. The power is integral within the bandwidth of the main
channel (default value: 2MHz). User can change the carrier bandwidth by using the numeric key, rotary knob,
direction key, or touch the panel menu.
Integ BW: Set the frequency bandwidth of the adjacent channel. The adjacent channel bandwidth is linked
with the frequency bandwidth. Users can change the adjacent channel bandwidth by the numeric key,
rotary knob, direction key, or touch the panel menu.
Offset Freq: The center frequency spacing between the main channel and the adjacent channel. Adjusting
the channel spacing will adjust the distance among the previous channel, the next channel and the main
channel at the same time. Users can change the adjacent channel spacing by the numeric key, rotary knob,
direction key, or touch the panel menu.
Offset Side: Specifies which offset side to measure.NEG,Negative (lower) sideband only.POS,Positive
(upper) sideband only.Both,Both of the negative (lower) and positive (upper) sidebands.
Meas Preset: Reset all parameters of the current measuring mode to factory setting.
