For sale:-  An HP 54502A 2 channel digitizing 400mhz scope, partly working but in need of repair to both input amplifiers.

 

It powers up and passes all self-tests as shown in the photos. The soft keys all work. The timebase and other functions work.  Cosmetically its in good condition for age, although one of the flip out feet is missing (it sits level when flat on the workbench). There is a carry handle that is concealed around the lower half of the front display rather than the more usual handles mounted on the case sides.

 

However, there is a problem in that both input amplifiers appear to be very low sensitivity and will need repair for the scope to be used properly. To get the waveforms shown in the photo I fed it  +/- 10v waveforms, but the scope is reading them as +/- 100mv or so, and therefore low amplitude signals will barely show.

 

It is therefore being sold as-is, in need of repair, or for spares.

COLLECTION

The buyer is welcome to collect, we’re based near J16 on the M1 / Northants.

 

POST / SHIPPING

If dispatched it will be sent in a new oversized double-walled box with inches of bubble wrap and additional protection where needed.   It will be sent out within 2 working days of cleared payment.

All items sent out will be by a tracked post/courtier service needing a signature on delivery, the exact service depends on your location. The tracking information will be supplied once enroute.

At the buyers request I will send items using FEDEX or DHL for the ultimate delivery method with the buyer paying the additional costs.

If you live in some far flung part of the World, then please let me know your location so I can obtain a quote.

The shipping cost quoted is for “post and packaging costs” and reflects the fact that this item will be well packed using new materials in a sensible double walled box with masses of bubble and tape, taking best part of an hour to wrap up, and up to a further hour for the round trip delivery to the couriers.

Please do NOT bid on this item if you intend to quibble the cost of P&P after winning it. I will not send an item like this in minimised packaging for the outright cheapest slowest method. Experience tells me this is a false economy …

 

PAYMENT

Item to be paid for by paypal or cash on collection within 48 hrs of auction end. If not completed within that time, I will either offer it to the 2nd highest bidder, or relist it and leave appropriate feedback.
