The processor on the A4 HP-IB assembly monitors the test set temperature with a comparator on the
A3

summing amplifier. The temperature sensor is located on the Al4 VTO/driver assembly. If the

temperature of the VTO/driver exceeds 85°C the HP 85101 displays the “Test Set Too Hot” prompt.

TEST SET TOO HOT means turn off the test set immediately. This mes-
sage is only a prompt. It does not turn off the test set.

Determine the reason for the prompt before again subjecting the test set to continuous use. Make sure

the fan is operating properly and is not covered by a piece of paper, etc. Make sure the fan and the side

panel air exhaust has at least 8 cm (about 3 inches) clearance, and top cover exhaust has at least 1.5 cm
(about 0.5 inches) clearance.

Power holes (power loss at a specific frequency) often result from faulty connections. Check the

following connections:

Test set rear panel (including the extension links)

Cables connected to the A3 summing amplifier and A5 Attenuator/Switch

Sampler cables

RF path connections from rear panel to front panel

Use a digital voltmeter to check the voltages given in Table 5-1. Use an oscilloscope to check AC ripple.
Use chassis ground as reference.
