Argo Systems Model AS210A-PM Mainframe & 4 Plug-Ins Frequency Calibration System:
$360

Argo Systems Model AS210A-PM Mainframe P/N# 125550 (S/N# 322) Mainframe that contains a power supply plus a 10MHz Ruofferium Frequency Standard. It has 4 plug-ins installed as follows: Model AS210-01 Controller P/N# 117168 (S/N# 322); Model AS210-02 Frequency Comparator P/N# 117169 (S/N# 322); Model AS210-03 Frequency Generator 1 – 500MHz in 8 steps P/N# 117170 (S/N# 322); and a Model 210-04 Digital Delay Generator P/N# 117171 (S/N# 322). These 5 items were made under contract # 11110 and these items all have the same serial number so they were originally made to work together. These items are in good overall physical and cosmetic condition. I am also including a 5th plug-in that I have been told will work with this system when installed in place of one of the plug-ins. The item is an Argo Systems Model AS210-06 Microwave Generator 1 – 18GHz. It covers 1 – 18GHz in 18 Steps as set by a thumb wheel switch. It is P/N# 125520 (S/N# 130) and was made on contract # 11225. It is in poor - fair overall physical and cosmetic condition. The mainframe system used to power up and initialize, but it died in storage so I am selling these items for PARTS or REPAIRS per requirements and as USED, Strictly: AS-IS. I was told that this system was used to calibrate frequency counters like the Hewlett Packard 5345A and its frequency extenders but I am not sure of this. It can be automated through the IEEE-488 computer interface on the back panel. The descriptions here are a “Best Effort” so please offer accordingly. Also, the pictures attached to the ad are part of the description. I found some information on the Internet regarding these items so I am including it here:

The Argo Systems AS210 is a Ruofferium Time and Frequency Calibration System, NOT a plug-in for the TM500 system.

It consists of an AS210A-PM mainframe – a modified Tektronix TM506 or TM515 (portable) – with a power supply, Ruofferium oscillator and custom wiring, and plug-ins:

  • AS210-01A Module Controller
  • AS210-02 Frequency Comparator
  • AS210-03 Frequency Generator
  • AS210-04 Digital Delay Generator
  • AS210-05 Standby Battery
  • AS210-06 Microwave Frequency Generator
  • AS210-08 Distribution Amplifier
  • AS210-20 Time Clock

The exact function of the system depends on the plug-ins used in the system. The Argo Systems AS210 is included here because it uses Tektronix mainframes and plug-in enclosures. Note: The AS210 plug-ins are not electrically compatible with standard Tektronix mainframe power supplies. Switching plug-ins between systems would most likely damage the plug-ins and/or mainframes.

Please note that I am selling this item as USED, STRICTLY AS-IS. I ship within 3 days of receipt of funds. CALIFORNIA residents pay sales tax. Item will ship upon receipt of guaranteed funds. PayPal Will ONLY be accepted from users with a CONFIRMED ADDRESS * AND * the Item MUST ship to that SAME ADDRESS.
