HP / Agilent 35665A Options Upgrade -

We offer an EEPROM programming service to activate the various options in the now obsolete and unsupported HP / Agilent 35665A Dynamic Signal Analyzer. The available programmable options for the 35665A include: 1D0, 1D1, 1D2, 1D3, 1D4, and 1C2 and are described as follows.

Programmable options enabled by EEPROM upgrade:
1D0 Computed Order Tracking (also requires hardware option 1C1 or ANA)
1D1 Real-time Octave Measurements
1D2 Swept-Sine Measurements
1D3 Curve Fit and Synthesis
1D4 Arbitrary Waveform Source
1C2 HP Instrument BASIC

Hardware options not enabled by EEPROM upgrade:
1C1 Adds 2 MByte Memory, requires memory board upgrade OEM P/N 35665-66586
ANA Adds 6 MByte Memory, requires memory board upgrade OEM P/N 35665-66587

We provide a new EEPROM (24C01) programmed with your instrument's serial number and all available programmable options are activated. The 24C01 replaces the obsolete 85C72 EPROM.

Installation:
The EEPROM is socketed and easy to replace. However, we recommend an experience electronics technician undertake this task, since some disassemble of the instrument is required to gain access to the EEPROM socket and proper ESD procedures must be followed to avoid damaging the instrument. At the same time we also recommend replacement of the nonvolatile memory backup battery (B200). The backup battery will require some de-soldering and soldering. Pictures of the disassemble and replacement are posted here. The "HP 35665A Memory Upgrade Installation Procedure" document (part number 35665-90060) describes the step-by-step procedure including tools for disassemble of the 35665A to gain access to the memory and cpu boards.

Pricing and part numbers:

Order P/N 35665A-01 = $65.00 (includes EEPROM & Battery)
Order P/N 35665A-02 = $55.00 (includes EEPROM only)

Part Number 35665A-01 includes pre-programmed 24C01 EEPROM with all available programmable options and serial number, plus one 3.6V, AA-size backup battery. Part Number 35665A-02 deletes backup battery. Quantity discounts apply according to the schedule below. NOTE: When placing order, we will need the serial number of the instrument(s) being upgraded.
