Preparing the Analyzer for Use

DC Power Cable and Grounding Requirements

The negative side of the dc input connector is not connected to chassis ground. In dc mode operation, the chassis will float. The chassis ground lug on the rear panel and the negative side of the dc input connector should both be connected to a known reference potential.

Two dc power cables are available—the HP 35250A dc power cable and the HP 35251A dc power cable with cigarette lighter adapter. Both cables contain a 30 amp, 32 volt fuse (HP 2110-0920).

The tip of the cigarette lighter adapter may get hot during use. After unpluging the adapter, be careful of the heat from the adapter’s tip.

Although shorter cables may reduce dc voltage loss, use the standard cables. The dc inrush current may pit the connector contacts in shorter cables.

AC Power Cable and Grounding Requirements

On the GPIB connector, pin 12 and pins 18 through 24 are tied to chassis ground and the GPIB cable shield. The instrument frame, chassis, and covers are connected to chassis ground. The input BNCs are floating unless ground mode is selected.

The analyzer is equipped with a three-conductor power cord that grounds the analyzer when plugged into an appropriate receptacle. The type of power cable plug shipped with each analyzer depends on the country of destination. The following figure shows available power cables and plug configurations.

used in two channel analyzers. 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.
