Controlling Multiple Test Sets
Installation and
Operation
Set each test set rear panel address switch to the address listed in Figure on
page 6-14, if configuring three or four test sets. Use the supplied test set
interconnect cable to connect test set number 1, J11 to the HP 8510. Use the
supplied test set interconnect cable to connect test set number 2, J11 to test
set number 1, J10. You may continue this test set “daisy chain” to include up
to four test sets if the total length of all test set interconnect cables does not
exceed 13 meters (about 40 feet). The last test set in the chain does not
require Option 001.
If the RF coaxial switches are not incorporated into the system, then the RF
input to the test set must be manually switched to the active test set.
Initialization at
Power-up
After power-up, configure the IF switches so that only one system test set is
active. Refer to the following procedure:
1. Check the active LEDs on all system test sets.
2. Check the HP 8510's expected test set address by pressing [
LOCAL
]
{
TEST SET
}. The address should match the address of the test set desired.
If not, change the address. See Figure on page 6-14 for recommended
addresses.
3. If unselected test sets are active (active LED ON), deactivate the test set
by temporarily addressing it then return to the desired address.
