Performance Verification
Preparation for Performance Verification
Prepare for Performance Verification tests by completing the following steps:
• Do a good installation “preflight” checkout on the 8510 system.
• Measure the environment temperature and humidity. The temperature must be
between +20 °C and +26 °C. Then the temperature cannot vary more than ±
1 °C after
calibration.
• Turn on the system components in the following order and allow one hour warm-up
time.
1. Source
2. Test set
3. 8510C
4. Controller
NOTE For the 8516, use only 834X016 or 8360X016. Older 8340 sources may require
modification before they work on the 8516. (Use upgrade kit 11875A, if
firmware is earlier than May 11, 1988.)
8350s may not pass phase on the 25 ohm mismatch verification standard. Try
Trim Sweep first or do a limited calibration.
