[Test-Equipment] FS: B&K RF generator, two old freq counters

[Avery Comarow]

Last chance before the auction place.

B&K E-200D RF signal generator: 100kHz-54MHz in five fundamental bands, 
32MHz-216MHz in two harmonic bands. Metered output, 20 dB/step attenuator, 
100kHz/1MHz calibrator (speaker for zero beating), good manual copy, output 
on all bands, 400Hz switchable modulation, clean manual copy, nice internal 
shielding. Not a Boonton or HP, but a step up from service grade. 
Appearance: VG (couple of small scrapes and a hairline crack in the meter 
cover). Will include test lead with clips at one end and Amphenol mike 
connector at the other. I paid $125 plus shipping. I'll take $90 plus 
shipping. High-res jpegs available.

Systron-Donner 6150A freq counter: 0-50MHz DC-coupled, 50Hz-50MHz 
AC-coupled. A, B, C inputs. 8-digit display. Purchased because I like 
Nixie-type displays. I’m ready to pass the counter on to another Nixie 
lover. No bad digits or segments, but otherwise operationally unknown. 
Appearance: VG. Original manual, not a copy­it cost me $40 separately. 
High-res jpegs available. $25 plus shipping without manual, $20 for manual 
($45 total plus shipping) if purchased with counter.

Hickok DMS 3200 mainframe with DP150 1MHz frequency counter/timer plugin. 
 From mid-’70s, advertised in Radio-Electronics and other service-oriented 
publications­a benchtop display (Hickok called it a “mainframe”) and a line 
of plugins: voltmeter, L-C analyzer, frequency counter, and other tools. 
Mine came with the freq counter plugin. Three big, bright digits. As with 
the Systron-Donner, I bought it because of the cool display. No bad digits 
or segments, otherwise operationally unknown. Appearance VG. No manual but 
easy to use. High-res jpeg images available. $25 plus shipping.
