Triaxial connector handling and contamination
Keep source-measure triaxial cable connectors (if applicable) clean and free of any foreign contaminants. Do not touch the
connector pins of the triaxial connectors. Contamination can cause current leakage in the source-measure signal paths to the
DUT, which can significantly degrade the test results.
Do not touch any connector pins or the areas adjacent to the electrical contacts of the triaxial
connectors; contamination will degrade the performance of the test system.
Cleaning
: Clean contaminated connectors with methanol or isopropyl alcohol, and then blow-dry them with nitrogen gas.
After blowing dry, wait several minutes before using.
Optional 9139A-PCA vacuum requirement
A 50.80 cm (20 in.) Hg (which is the same as 40.73 PSI), with a hose connection of .64 cm (1/4 in. ) outside diameter and .32
cm (1/8 in.) inside diameter.
Lockout/Tagout
For maximum safety, always perform a lockout and tagout procedure by removing power from the entire test system and
discharge capacitors before connecting or disconnecting cables or any instrument, including the device under test, while
power is applied. When you perform lockout and tagout procedures, make sure that you note all warning labels on the
cabinet and instruments (see next figure).
Figure 22: Hazardous warning label
Severe personal injury or death due to electric shock or electrocution may result if power is
not removed before working inside the cabinet. Always disconnect the cabinet line cords from
the AC line power receptacles before opening the system cabinet. Also, never turn on the
system until all connections and safety grounds are installed.
When you perform removal and installation procedures, or maintenance on the system, lockout by placing a padlock through
the bracket by the PDU breaker and tagout as appropriate.
