5.16 [Marker Fctn] Marker Function
• Executes specific marker soft menu.
5.16.1 [Function Off]
Turn off marker measurement function.
5.16.2 [NdB On Off]
Enables the N dB BW measurement or sets the value of N. The N dB BW denotes the frequency difference between points
that are located on both sides of the current marker while the amplitude falls off (N<0) or rises (N>0) N dB separately,
Key points:
• When the measurement starts, the analyzer will search the two points which are located at both sides of the current point
and are N dB amplitudes smaller or greater than the current point, and display the frequency difference between the two
points.
•
You can use the numeric keys, knob or direction keys to modify the value of N, 3 at default.
5.16.3 [Marker Noise On Off]
Turn on or off the frequency noise function. The function of marking noise is applied to the selected cursor, and then the noise
Power Spectral Density at the cursor is read. When turned on, the average noise level read at the frequency scale is
normalized to 1 Hz bandwidth for noise power.
5.16.4 [Freq Count►]
Activate the frequency counter function and display the count results in the upper right corner of the screen. The counter
counts only the signals that are displayed on the screen. The frequency count also pops up an additional counter function for
the soft menu, including [Freq Count On Off ].
1) [Freq Count On Off]
Turn on or off the frequency counter mode. This function is invalid when the trace signal generator is activated. The count
value is displayed in the upper right corner of the screen.
2) [Resolution]
Counter resolution is divided into 1 kHz, 100 Hz, 10 Hz, 1Hz. Changing the counter resolution can change the counter
accuracy. The higher the resolution, the higher the counting accuracy.
3) [Return]
Return to the previous menu.
5.17 [Meas] Measurement
Provide a variety of advanced measurement functions, pop-up spectrum analyzer built-in and user-defined measurement
function soft menu, turn on or off the time spectrum, adjacent channel power measurement, channel power measurement,
occupied bandwidth, Pass-Fail measurement menu.
5.17.1 [Measure off]
You can directly close the currently running measurement function, you can also choose to close the measurement menu.
5.17.2 [Time Spec On Off]
Turn on time spectrum measure mode.
5.17.3 [ACPR On Off]
Turn on or off the adjacent channel power measurement. Press [Meas Setup] to pop up the parameters of the adjacent
channel power measurement soft menu. The adjacent channel power is used to measure the ratio of the adjacent channel
power of the transmitter. The absolute value of the main channel power and the absolute value of the adjacent channel power
are obtained by the linear power integration method, so that the adjacent channel power ratio is gained.
