There are three versions: | |||
* '''PS501''' has coarse/fine potentiometers for setting the variable output voltage. | |||
* '''PS501-1''' has a 0–10/10–20 V switch and a 10-turn pot with mechanical voltage readout. | |||
* '''PS501-2''' has coarse/fine potentiometers, and additionally features an analog meter to monitor voltage or current. | |||
All versions have a 0–400 mA current limiting pot and an output switch. | |||
The 0–20 V / 400 mA output is floating, the fixed 5 V / 1 A output is ground referenced. | |||
Two special modified versions of the PS501-1 exist: | |||
* '''PS501-1 MOD 730E''' is a modified version to power the strain gage adapter [[015-0169-00]] or other transducers. The strain gage adapter was initially powered by the [[3A10]] differential plug in for the [[561]] or [[564]] oscilloscopes. When the production of this oscilloscope series was terminated in 1975, the modified PS501-1 MOD 730E became available in 1977 as a replacement power supply, and was produced until 1985. | |||
* '''PS501-1 MOD 730F''' is a modified version to provide power for the 015-0108-01 Rotational Function Generator (RFG) and to condition its output signals to be connected to the modified [[7B53A]] MOD FB time base. The RFG is described in the [[Engine Analyzer]] manual with schematics. <br />The [[3A74]] MOD 730A vertical amplifier and [[2B67]] MOD 730A time base were originally used in a [[561]] or [[564]] oscilloscope as part of the Tektronix [[Engine Analyzer]] System. When the production of this oscilloscope series was terminated, the modified PS501-1 MOD 730F became available as a functional replacement for generating the horizontal signals for the gated X-Y display of the [[7B53A]] MOD FB timebase. The [[Media:Physical Measurements Handbook.pdf | Physical Measurements Handbook ]] has descriptions of the available tranducres and components, which before were described in the [[3A10]] manual. | |||
