This is a used oscilloscope. I do not know its age, but it looks like it has had little use. Although I believe it is fully functional, I cannot guarantee it will work for all applications or that it is completely accurate. I checked both channel 1 and channel 2 inputs over a wide range of frequencies, using sine, square and sawtooth waves, and as near as I can tell it works very well. I have not checked the calibration, external trigger, Z axis input or other functions. The screen gives a good trace, does not appear to have been burned (I.e. by being left on with an intense dot or curve). A copy of the manual is included. I will answer any questions as best I can, but please understand that I am by no means an expert in working with electronic equipment.
Some of the specifications are:
150mm rectangular CRT, internal graticule scale
Vertical sensitivity: 5mV/div to 5V/div (all bandwidths) 0.5mv/div to 2mV/div (5MHz, Mag x 10) variable in 10 steps 1-2-5 sequence
Maximum input 600V (DC + AC peak to peak)
Horizontal: Trigger sweep and automatic trigger sweep, 0.2us/div to 0.2s/div, 1-2-5 sequence, 19 steps with continuous adjuster
Display modes CH 1, CH 2, chop, alternate, add
The probe is an RSR Electronics 05SPAK110, new (still in the package). I have one just like it and even though it is not a high-end probe it works fine when adjusted properly. You can check it out at http:// /tld_k110.htm.
Scope is not guaranteed. The probe is new but is not guaranteed.
