Equipment

At SpecialtyCircuits LLC, we are proud of our collection of test equipment. Although some of them may seems very old secondary market purchase. They can provide a very unique testing scenario that are ignored in the modern digital era. 

So here we go, some antique show. 

  1. Tektronix 7104 with dual 7A19 and 7B10, 7B15 delaying time base.
  2. Tektronix 7854 digital storage oscilloscope with 7S12 sampling/TDR capability. Measurement up to 14GHz bandwidth
  3. LeCroy SDA11000. High bandwidth real-time oscilloscope capable of 6Hz/11GHz
  4. Tektronix 792 Spectrum Analyzer. Spectrum analysis up to 26GHz
  5. HP RF signal generator. 2-20GHz signal generator with ovenized crystal frequency reference. 
  6. Preamble(LeCroy) DA1855A differential amplifier
    This is the very last commercially sold traditional differential amplifier, with variable gain, bandwidth, built-in voltage source etc. No company sells differential amplifier anymore. The only ones left are the active differential probes. 
    DA1855A- the last commercial differential amplifier
  7. Tektronix 7A13 differential comparator(amplifier)
    This is the predecessor of Preamble DA1855A. The designer, John Addis, left Tektronix and later started Preamble. More history can be found at TekWiki. 7A13 had a bad name "Comparator". It confuse people to think this is a digital output device. It is a analog amplifier that can be used to compare two signal differentially. That is what "Comparator" means. 
  8. Tektronix 7A22 differential amplifier
    This is the low bandwidth, high gain differential amplifier. With it, you can measure 40mV square wave with a 1000X high voltage probe. 
  9. Keithley xxx, Electrometer, capable of attoamp resolution. 
  10. ADCMT 7480T 8.5 digit DVM. Fast 8.5 digit resolution measurement at 2SPS. 
  11. Keithley 2636A Source Measurement Unit. Dual channel, capable of pA resolution up to 200V
  12. Agilent DS06104L
  13. Agilent DSO5014
  14. Tektronix TDS3054B with battery. Isolated measurement at 500MHz
  15. Vapor Phase soldering oven. Beautiful solder wetting for small volume production.
  16. Various other oscilloscope, signal generator, power supply, voltage source.
