Revision as of 03:30, 12 July 2019

This is about the Motorola R2001 series of test equipment from the earl/mid 1980's.

Contents

Options

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.

File:R2001D Flyer.pdf

The 2001D was first offered in 1984/85 as the following options:

Model Description
R-2001D Basic Model
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:

Model Description
R-2001D Basic Model
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-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-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

Board options

I call this board options as through out the life of the 2001, different boards were produced.

Firmware

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.

Audio Synth Board - U11 Rev 8443

Revision 8443, MM2716 from A-10 audio board. Likely this is a fixed "rom as logic lookup" use.

Technical notes

Extender Cards

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.

Scope conversion

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.
