Getting Started

Figure 2-2 Connecting the Test Set to the Agilent 8753D Option 011

Network Analyzer

After all the proper connections have been made, turn on the test set

using the front panel line switch. The front panel line switch

disconnects the mains circuits from the mains supply after the EMC

filters and before other parts of the instrument.

NOTE For accurate, repeatable measurements, be sure to let the test set warm

up for at least 2 hours. It is recommended that the test set not be

turned off on a regular basis. For the most stable and accurate

measurements, leave the test set turned on at all times.

Setting the Test Set Address Switch

The test set is shipped with the GPIB (HP-IB) address set to 12, which

sets the parallel address to 0 as in Figure 2-3 on page 2-4. Refer to

“Introduction” on page 5-2 in this manual for the definition of the

parallel address.

To set the GPIB (HP-IB) address, set all five switches so that the sum of

the switches in the on or 1 position equals the desired address. In the

example below, the two switches in the on position are 8 and 4, thus the

GPIB (HP-IB) address of 12.

To set the parallel address, use only the number 1 switch. Therefore,

the only possibilities for parallel port addressing are an address of

0or1.

When GPIB (HP-IB) is used, the parallel address is ignored.
