Hi all,i was miss sold a tek 2430 ,instead of beeing a 2430A as advertised,turns out it isnt the A model but a 2430 non A,ive beeing looking at signals from a sig gen on this,i want to be able to display the frequency in mhz etc,i can see the % duty cycle etc but cant seem to get it to display the frequency,is it posible with this non A version?,i know the A version has more math functions,is displaying frequency one of them?,this was the original listing:https://www.ebay.co.uk/itm/Tektronix-2430A-Oscilloscope-/294643654575?nma=true&si=pafAtsKxNpZVz9IsNtJq%252FWUFbig%253D&orig_cvip=true&nordt=true&rt=nc&_trksid=p2047675.l2557
The poor display was just dirt behind the blue screen filter,the other issue was a FPP self test fail,that was fixed by replacing the LTC-7P nv ram battery,being able to display frequency was one of the main reasons for buying this,if it cant be done i may send it back for a refund as it was not as listed,TIA.
