Stanford Research DS360 Ultra Low Distortion Function Generator w/ Digital

Current Stock:

Product Description

Manufacturer: Stanford Research Systems SRS

Model: DS360

Condition: Used. This unit is in Good cosmetic condition from a few feet away. Up close you will find lots of scuffs and scratches in the paint, including some scratches all the way to metal. The photos show the exact item(s) the buyer will receive.

Notes: This generator is in MOSTLY-working condition.  It was not calibrated at its last cycle as they said it failed square wave linearity.  We think they are referring to the tendency of square waves to turn into round waves (electronics joke) at high frequency.  At low frequency, square waves are sharp and ring a bit, and are still not square on our oscilloscope. Sine waves look nice at all frequencies until nearly maximum output voltage and then the sine waves get ugly too.

At very high output voltages, the waveforms are badly distorted.  Sine waves look ok until about 30Vpp, but square waves just get worse distortion.  As amplitude increases, square waves start to overshoot, and then the overshoot turns into nasty spikes.  At very high amplitude, sine waves start to look rough, and then they get almost as jaggy as square waves approaching maximum output level. The amplitude indication on the generator is only a rough indication. As voltage increases, the actual peak-to-peak level diverges from the indicated level, as much as several volts off at maximum output.  At very low voltage, a few millivolts out, the signals start to look a little fuzzy.  The display is bright and clear, very easy to read. The control knob and buttons respond to user inputs as expected. No other testing was done.

Photo #4 shows:

  • Sine waves look good all the way to maximum frequency
  • Square waves are not square at maximum frequency
  • Our frequency counter reading the output frequency of your generator, 10Hz (minimum for our counter) and 200kHz
  • Sine waves look good even at high output levels
  • 2-tone superimposes one signal on another
  • White and pink noise output

Photo #5 shows:
  • Square waves at lower frequency are still not proper squares
  • Bad distortion at very high amplitude on square and sine output waveforms
  • Very-low level signals are not sharp on our scope
No manuals, cords/cables, or additional items are included if not listed or shown.
