HP1631D Logic Analyzer - Scope
I own a HP1631D Logic Analyzer (build 1984), with 40 channels State-, 16 channel Timing-Analysis and 2 analog channels (oscilloscope). The HP1630 is a pure Logic Analyzer, the HP1631 has in addition an oscilloscope plug in.
The oscilloscope has a bandwidth of 50 MHz and a sampling rate of 200 MHz.
As accessory I have a preprocessor for RS232, RS449 and GPIB bus and the suitable Inverse Assemblers.
The draw back is the wight (18 kg), power consumption (275-300 W) and the noise (63 dB(A)).

Take care, they changed the fan from 230 VAC to 12 VDC with the new PSU, page 7-12 in the service manual (Thanks to Anders):
- 1630A from 2715Axxxx
- 1630D from 2720Axxxx
- 1630G from 2602Axxxx
- 1631A from 2714Axxxx
- 1631D from 2713Axxxxx
Fan noise reduction
It is possible to reduce the noise of the fan. To open the housing, you have to loosen (center one) or remove (feet) the screws, which are marked with an red arrow in the pictures to the right.

In order to reduce the noise of the equipment I first have to figure out, what fan is build in
Fan, build in: Papst Typ 4658N, 230 V, 18 W, 50 / 60 Hz
- Turn per minute: 2650 rpm (50 Hz)
- Air flow: 100 qfm / 160 m3/h (50 Hz)
- Noise: 47 dBA
- Size: size: 119 x 119 x 38 mm, mounting hole distance 105 mm
- Connection: contact 3 x 0,5 mm
As lower noise alternative:
- NMB 4715 MS-23T-B5A, 230 V, 15 W
- Turn per minute: 2600 rpm
- Air flow: 88.2 qfm / 150 m3/h
- Noise: 37 dBA (50 Hz)
- Size: size: 119 x 119 x 38 mm, mounting hole distance 105 mm
- Connection: contact 3 x 0,5 mm
As a result, the NMB fan is less noisy. Measuring the noise in 1 m distance gives:
- Original (Papst) 54 dBA
- Replacement (NMB) 50 dBA

Preprocessor
You can buy from HP a General Purpose Probe Interface HP10269B, which takes the Pods from the logic analyzer. Then you can plug in underneath specific interfaces, in my case a Bus Preprocessor, see picture on the right.
The most versatile plug in board is the Bus Preprocessor HP10342B which can analyze HPIB, RS232 and RS449 bus signals. The bus will be connected via flat cable with a standard D-plug. An overlay foil for the preprocessor helps to match the right pods to the right place, suitable to the application.
You can get software from HP (Inverse Assembler) which shows the signals of the analyzed bus in clear text.

Inverse Assemblers are available for example:
- MC6909, MC68000, 8085, Z80, etc.
For the Bus Preprocessor the follwing files are available:
- HPIB bus - IHPIBc.#fffe (Configuration), IHPIBi.#fffe (Inverse Assembler)
- RS232 bus - IRS232Cc.#fffe (Configuration), IRS232Ci.#fffe (Inverse Assembler)
- RS449 bus - IRS449c.#fffe (Configuration), IRS449i.#fffe (Inverse Assembler)
As an example the GPIB analyze text screen (command Beep) with Bus Preprocessor HP10342B and Inverse Assembler (IHPIBc & IHPIBi):
