The following are common problems about S3331 handheld spectrum analyzer.

1. Start S3331 but the screen does not light:

Please following the procedures below

(1) Check whether the fan is running:

A. If the fan runs normally, it is possible that the display cable is loose. Please contact Saluki.

B. If the fan does not run, the instrument does not start normally. In this case, check steps (2), (3) or (4).

(2) If using battery powered: Make sure the battery is in good condition and installed correctly.

(3) If the instrument is powered via adapter: Make sure the power adapter model is correct and working well.

(4) If the power is ok, but the instrument does not work, the fuse inside may be burned. Please contact Saluki.

2. Keys not respond or the response is incorrect:

(1) If all the keys are not responding, it is possible that the keyboard cable is loose.

(2) If the key value is wrong, there may be damage on keyboard, please contact Saluki to repair.

3. No signal display after normal power on:

If the monitor does not display the signal, please follow the steps below:

(1) Connect 10MHz reference outputs port to RF input port

(2) If there is no signal Display, there may be machine hardware failure, please contact the manufacturer to solve.

4. The frequency of the signal display is not accurate:

During the measurement, the read signal frequency exceeds the acceptable error range or the signal is shaking on the display:

(1) Check if the input signal is stable, and if so, check in step 2.

(2) Check whether the internal and external reference of the spectrum analyzer is normal, and select the reference for internal reference or external reference according to different test conditions: Press [Frequency] [Frequency reference internal external].

(3) If the problem is not solved, please contact Saluki.

5. The amplitude of the signal is not accurate:

The amplitude of the signal is inaccurate.

Recalibration: Set a signal generator frequency 440MHz, power -20dBm, connect this signal to the RF analyzer RF input port, click: [System] [Next] [Next] [User calibration] [Start calibration].

If the problem is not solved after recalibration, please contact Saluki.
