Performance Test

6-5.

When received, the 2640A/2645A is calibrated and in operating condition. The following Performance Test procedures are provided for acceptance testing upon initial receipt or to verify correct instrument operation. The performance tests must be performed in sequence.

If the instrument fails a performance test, the instrument requires service or repair. To perform these tests, you will need a Fluke 5700A Multifunction Calibrator and several other pieces of equipment meeting the minimum specifications given in Table 6-2.

Each of the measurements listed in the following steps assume the instrument is being tested after a 1/2 hour warm-up, in an environment with an ambient temperature of 18 to 28°C, and a relative humidity of less than 70%.

Warning

The 2640A/2645A instrument contains high voltages that can be dangerous or fatal. Only qualified personnel should attempt to service the instrument.

Configuring the Performance Test Setup

6-6.

Configure the performance test setup as described below. The performance test requires a complete network connection between the host computer and instrument under test, including a host computer Ethernet interface and installation of NetDAQ Logger. If you have not yet configured and tested a network connection for the host computer and instrument, complete the appropriate installation procedure for your network configuration before conducting any performance testing.

1.Connect the Instrument and the Host Computer Connect the supplied 50-ohm coaxial cable, with a BNC "T" or "Y" and 50-ohm terminator, between the host computer BNC Ethernet port and the instrument BNC Ethernet port. The 50-ohm terminator with the ground lead is used at the instrument with the terminator ground lug connected to the ground terminal adjacent to the BNC port (Figure 6-2). See Chapter 2 for other interconnection methods.

2.Connect the 5700A to Channel 1 Connect a cable from the Output VA HI and LO connectors of the 5700A to the Universal Input Module terminals for channel 1 connecting the 5700A HI to terminal H and LO to terminal L. Insert the Universal Input Module into the instrument under test (Figure 6-3).
