If the analyzer will not power up

Agilent 35670A	Preparing the Analyzer for Use
	If the analyzer will not power up

If the analyzer will not power up

Check that the power cord is connected to the Agilent 35670A and to a live power source.

Check that the front-panel switch is on ( l ).

Check that the rear-panel AC/DC power select switch is properly set.

Check that the fuse is good.

GSee ‘’To change the fuses’’ on page 2-10.

Check that the analyzer’s air circulation is not blocked.

Cooling air enters the analyzer through the right side and exhausts through the left side and rear panel. If the analyzer’s air circulation is blocked, the analyzer powers down to prevent damage from excessive temperatures. The analyzer remains off until it cools down and its power switch is set to off ( O ) then to on ( l ).

Obtain Agilent service, if necessary. See ‘’Need Assistance?’’ at the end of this guide.

The A12 BNC assembly routes the signals connected to the Channel 1 BNC connector and Channel 2 BNC connector to the A1 Input assembly. The A12 BNC assembly also routes the source signal from the A5 Analog assembly to the Source BNC connector. The signal connected to Channel 1 should be between 0.19531 Hz to 102.4 kHz in single channel mode and between 0.097656 Hz to 51.2 kHz in two channel mode. The signal connected to Channel 2 should be between 0.097656 to 51.2 kHz. For both channels, the signal’s amplitude range must be between +27 dBVrms and –51dBVrms for full scale measurements. The source output signal can be random noise, burst random noise, periodic chirp, burst chirp, pink noise, or fixed sine.
