Tektronix DSA602A Digitizing Signal Analyzer Part 1

I recently had the opportunity to purchase one of these units, and I am thoroughly enjoying the process of  checking its operation and getting to know how to use it.  This unit is a laboratory grade, very accurate digitizing oscilloscope from about 1990.  From the Tek Wiki entry:

Inputs 3 amplifier bays, up to 12 channels (using 11A34 plug-ins)
Resolution 8 bits; averaging of N acquisitions increases by log2(N) up to 14 bits
Display resolution 50 pixels/Div
Sample rate DSA601, max 1 GS/s; DSA602, max 2 GS/s (one channel, left plugin)
Record length 512 to 32768 samples
Sweep rate 50 ps/Div  to 100 s/Div
ENOB 7.2 bit up to 10 MHz, 6.3 bit @ 250 MHz, 5.7 bit @ 500 MHz, 4.5 bit @ 1 GHz
Screen magnetic deflection color computer monitor, 10″ diagonal (130 mm × 168 mm), 552×704 pixels, 22×11 infrared touch-screen grid
Power 90-132 V or 180-250 V, 48-72 Hz, 465 W (DSA601A) / 585 W (DSA602A)
  • Automated signal measurements (rise, fall, period, frequency, width, delay, phase, duty cycle etc.)
  • Averaging
  • “Act on Delta” acquisition
  • X-Y mode
  • FFT: complex, forward and reverse, max. 16384 points; windows: Rectangular, Bartlett, Hanning, Hamming, Blackman, Blackman-Harris
  • Hardcopy to various Tek, Epson and HP printers or HPGL plotters, via RS-232, GPIB, parallel port or disk file

The following images highlight my experiences thus far:

Part 2 of my investigation of the DSA602A is on the way.
