Hello all,
I recently got ahold of an HP 10529A logic
comparator but I am not sure how to use it.
The unit came with a self test card and a card with
textool socket 10529-60014.
When I insert the test card and supply 5V to the
card connectors the logic comparator LEDS blink shortly with a 2 second interval
or something. If I also connect the logic clip on top of the "dummy" IC I get a
long blink (approx 1 sec) and then still the short blink. I don't know if this
qualifies as "normal" behaviour.
To test the 10529A comparator I tested with a
Wonderboy PCB. I insert the appropriate 74LS chip in the textool socket (pin 1
aligned to the "1" mark (near the SW error led)) but no matter how I fiddle
around with the dip switches or COMP/CLIP switch I always get red comparator
LED's to remain turned on (I expected either all of them to light up or remain
off). I have tried with different 74LS chips on different locations but I can't
get any decent result out of this.
Can anybody tell me how to use this 10529-60014
thing (no manual here) or tell me what I am doing wrong ? A short description of
what the dip switches and comp/clip switch are for would be
welcome...
Best regards,
Filip
