First-time Power-on of the Spectrum Analyzer

The Handheld Spectrum Analyzer is supplied by power adapter or internal battery. When battery is fully charged, internal battery can supply power for about 4 hours if spectrum analyzer works normally. Battery of this device can’t store power during transportation, so, such battery must be charged before first-time use. Battery can be charged while power adapter provided along with equipment supplies power to instrument.

Battery not only can be charged when instrument is power on, but also when it is power off. Time for charging is about 4 hours when instrument is power on or off.

Troubleshooting

Black screen and without any display after start-up

1)Check whether fan works normally:

  1. If fan works normally, connection wire of display screen may be loose;
  2. If fan doesn’t work normally, instrument is not normally started. At this time, please handle according to step (2), (3), or (4).

2)If battery supplies power: confirm whether battery is in good condition and has been correctly  installed.
3)If adapter supplies power: confirm whether model of adapter is right and such adapter works normally.
4)If power adapter works normally, fuse inside instrument may be burnt out. Please contact with manufacturer for repairing.

No response or error of key value by pressing keys

 In case of error of key value, keyboard may be broken. Please contact with manufacturer for repairing.

No signal displayed after normal start-up

Steps: set frequency and power of signal generator respectively as 30 MHz, -20 dBm, connect this signal with RF input; or connect spectrum analyzer’s 10 MHz reference with RF input; if there is still no signal displayed, equipment hardware failure may occur. Please contact with manufacturer.

Signal frequency inaccurately displayed

When test signals, if signal frequency read out is beyond allowable error limit, or signals shakes on the screen:

  1. Check whether input signal is stable. If yes, please check according to step (2);
  2. Check internal and external references of spectrum analyzer is normal. Select reference as internal or external reference depending on different tests: press Frequency [Frequency reference Internal External], if frequency read out is still inaccurate, lock-loss may occur to internal circuit of spectrum analyzer.

Signal amplitude inaccurately displayed

If displayed signal amplitude is inaccurate, please check according to following steps:

  1. Check whether signal amplitude input is right. If yes, please check according to step (2) or (3);
  2. Re-calibration: set frequency and power of signal generator respectively as 440MHz, -20dBm. Connect this signal to spectrum analyzer’s RF input, and click System [Next page] [Next page] [User calibration] [Start calibration] in turn.
  3. If signal amplitude displayed is still inaccurate after re-calibration, hardware failures of spectrum analyzer may occur.

Maintenance and Cleaning

Please don’t place instrument in the sunlight for a long time.In case it is unused for a long time, please place instrument in a dry and cool place.Please keep instrument away from any corrosive liquid, to avoid damage of instrument.

Please clean instrument depending on actual service condition. Method is as follows:

  1. Disconnect power, and close instrument.
  2. Use wet (not dripping) soft cloth (gentle detergent or clean water can be used) to wipe off dust outside instrument. When clean LCD display screen, please don’t scratch transparent LCD protection screen.
