The N4960A serial BERT controller features high-quality SMA
connectors for the front and rear panel input and output connections
while the N4951A pattern generator and N4952A error detector use
2.92 mm. The N4951B pattern generators use type 2.4 mm connectors
for data output and SMA for auxiliary input/output connectors.
Connector damage will degrade signal fidelity.
Use high quality SMA-connectors on the SMA ports. Always leave dust
jackets on unused ports. Tighten the connectors to 8 in-lbs (90 N-cm)
to assure proper mating.
Refer to the N4960-90030 N495xA through N498xA Connector Care
Reference Guide at www.Keysight.com/find/N4951A.
Inspect the connectors for the following:
•
Worn or damaged threads
•
Scratches to mating surface
•
Burrs and loose metal particles
•
Dust or foreign material in the space surrounding the center pin
•
Ensure that female contacts are straight and aligned
Clean the connectors as described in the following procedure. Cleaning
connectors with alcohol shall only be done with the instruments power
cord removed, and in a well-ventilated area. Allow all residual alcohol
moisture to evaporate, and the fumes to dissipate prior to energizing the
instrument.
1. Remove any dust or loose particles using a low-pressure air
source.
2. Moisten a lint-free swab with isopropyl alcohol. Do not saturate
the swab.
3. Minimize the wicking of the alcohol into the connector structure.
4. Clean the mating plane surfaces and threads.
5. Allow alcohol to evaporate, and then use a low-pressure air
source to blow surfaces clean.
6. Make sure no particles or residue remains.
7. Inspect connector for damage.
On power on, the instrument always returns to the factory preset
settings, listed in
8 Appendix A Preset
return to last used settings may save them in one of the 5 saved settings
locations, and recall them on power on.
