Service Test Equipment

The test equipment required for the TME based N7841A test and adjustment software is listed in the
N7841A help file.
The following additional test equipment is recommended when servicing the N9912A analyzer:
• Main Battery—Required if the analyzer is returned for service without a battery. Refer to
page 6-14 for part numbers.
• USB flash drive—Used for firmware upgrades, option installation, etc. Also known as USB memory
stick. Must be 128 MB or larger.
• Small, free-standing fan—Used to cool the analyzer if internal temperature is too high. See "DUT
Warmup" in the "Getting Started" section of the N7841A help file for usage instructions. Generic small
office fan of approximately six inches in diameter is sufficient.
• Type-N male cal kit—Tee cal kit, part number 1250-3607, is recommended. This matches the default cal
kit definition stored in the analyzer. Cal kits 85032E/F or 85054B/D may be substituted.
• Mini SD flash card—Required to re-load firmware onto the A6 SOM board. A "mini" sized Secure Digital
(SD) flash memory card is between "standard" and "micro" sizes. The memory size must be at least 64
MB and not greater than 2 GB. This card is not available from Keysight. To identify a supplier, search the
Web for "mini sd card".
• Stereo headphones or ear buds—May be used to troubleshoot sound output if there is a problem with
the internal speaker.
