There were several A/B/C units in the 2001 series before the D came out in 1984. The earl units were offered for sale beginning in 1980, and lack some of the features of the later units. I'm not sure what they lack other than the modularity and the frequency tuning control of the D series.
The 2001D was first offered in 1984/85 as the following options:
|R-2001D/HS||Basic Model with 10MHz OCXO|
|R-2002D/HS||IEEE 488 (GPIB/HPIB) and 10MHz OCXO|
|R-2008D/HS||Cellular (AMPS) Option and 10MHz OCXO|
|R-2009D/HS||Cellular (AMPS) Option, IEEE 488 (GPIB/HPIB) and, 10MHz OCXO|
At some later date (1986?) the other options were introduced:
|R-2001D/HS||With high stability oscillator|
|R-2002D||With IEEE·488 option|
|R-2002D/HS||High stability oscillator and IEEE·4BB Bus option|
|R-2004D||With Motorola DES option|
|R-2004D/HS||High stability oscillator and Motorola DES option|
|R-2005D||With Motorola SECURENET option|
|R-2005D/HS||High stability oscillator and Motorola SECURENET option|
|R-2008D||With cellular option|
|R-2008D/HS||High stability oscillator and cellular option|
|R-2009D||With IEEE·4BB Bus and cellular options|
|R-2009D/HS||With high stability oscillator, IEEE-48B Bus and cellular option|
|R-2010D||With UK cellular option|
|R-2010D/HS||High stability oscillator and UK cellular option|
|R-2011D||With IEEE-488 Bus and UK cellular option|
|R-2011D/HS||High stability oscillator, IEEE·488 Bus, and UK cellular option|
|R-2012D/HS||No idea what this is|
|R-2014D/HS||No idea what this is|
|R-2021D||With Motorola Trunked Radio option|
|R-2021D/HS||High stability oscillator and Motorola Trunked Radio option|
|R-2045D||With Motorola DES and SECURENET options|
|R-2045D/HS||High stability oscillator and Motorola's DES and SECURENET options|
|R-2048D/HS||High stability oscillator with DES/SECURENET and Cellular Options|
I call this board options as through out the life of the 2001, different boards were produced. The A12 and A13 slots can take any option board, but some combos require the GPIB card.
The service manual identified the following options:
|Option A||Cellular Tel Test Board||01-P22120E001|
|Option B||IEEE/Remote Interface Board||01-P22130E001|
|Option C||Secure Comm Board||01-P23360K001|
|Option D||Trunked Radio Test Board||01-P229000H001|
|\900||Enhanced Duplex Generator Board||01-P22338K001|
|AT-1||Remote control attenuator||01-80343B84|
\900 this was an option which added a 39, and 55 MHz offset to the duplex generator (in addition to 45 MHz and 0-10 MHz).
The serial numbers follow the standard Motorola way of expressing the model and moanufacture date
A standard Serial number will be 415KNV0069. In this the 415 is the model type, K is a check digit, N is the Year, V is the month and 0069 is the number made in that month.
There's a bunch of manual all over the net, some I've scanned, others from other people. Some scans are better than others, I've OCR'd and cleaned up what I've found to the best of my abilities.
- 33 MiB, rough scan and source
- 60 MiB, Good Scan, most complete.

The below firmware images have been read off the PROMs inside the respective modules. I'm not sure what's what, so I've broken it out by the monitor it came from. Any additions would be helpful.
- Version 05A, M27256 Image from M40 on A14 CPU board June 1995
- Version 05A, M27256 Image from M41 on A14 CPU board June 1995
- Version 05A, M27256 Image from M42 on A14 CPU board June 1995
- Version 09A, HN4827128 from A12 Secure board marked "SECURE VERSION 09A T.E.S.D. May 1995"
- Revision 8443, MM2716 from A-10 audio board. Likely this is a fixed "rom as logic lookup" use.
The original extender cards are not available from Motorola. They were flexible and you were able to lay the test board on top of the unit to trouble shoot it. The card edge connectors are .1" spacing and were manufactured by Sullins Microplastics. I've had good success with after market flexible cards from eBay/china.
Fuse on Antenna Input
The antenna input is designed to take a 1/8 amp axial Picofuse made by Littlefuse - 0251.125MXL
Digi-Key has them F2308-ND
I've also used the smaller 1/16 Amp Fuse, the smallest value they offer in the 251 series. It's about 3x the cost however. Digi-Key F2307-ND
Tracking generator function
This was a little Easter Egg left in the system. One can get a spectrum analyzer and tracking generator function in the spectrum mode. This allows the use of a return loss bridge to measure return loss.
Simply set the duplex generator offset to 0 and enable the duplex generator in the spectrum analyzer mode. The offset oscillator will sweep in sync with the analyzer.
Note this is not calibrated, but it will work. There are limits to the general poor preformance of the built in spectrum analyzer.
Based on a note it's possible to use an external scope with the unit if the internal CRT dies.
CRTs are very rare for the R2000 series. It is, however, possible to use an Ocilloscope as a replacement, since the original scheme used an electrostatic CRT: Here is how I have connected an ocilloscope to the R2001. The scope is used as a replacement for the CRT. The scope must have X, Y, and Z inputs. X = Vertical. Y = EXT Horizontal input. Z = Blanking input, which is often found on the back panel of the scope. The video will be inverted (negative) unless you construct a simple video inverter. Connections to the R2001: All connections are to test points on the A-2 board which is next to the CRT. The test points are in order as noted. Also note that the LV supply will not operate with out the HV supply connected. R2001A,B,C: Vert: TP4 Horiz: TP1 Z (video): TP8 TP1 is toward rear of the chassis. R2001D: Vert: TP1 Horiz: TP6 Z (video): TP1 TP1 is toward the front of the chassis. Set the scope for Ext Horiz, set Vert and horoz gains for the desired scan. Adjust scope Intensity, and 2001 Intensity for adequate display. The only R2001 front panel control which will be inoperative is the Focus.
I took the following pics of a R2005D/HS I repaired
