The side frames are common to many instruments of the period. Some power supply parts are common to the 5246, 5245 and 5248 (the 5246 is a skun down 5245, the 5248 goes to 150MHz as I recall). The 5245L suffers for frequency comparison because it has only a period average (no Time Interval Average) and the period average is only good to 300kHz. The 5262A doesn't support averaging either, so it or the 5263A (same case I think) will only offer resolution of 100ns. The 5345A will offer 2ns single shot time interval resolution and can average over 1000 intervals giving 2ps resolution. The ideal is the 5370A/B which has a single shot TI resolution of 20ps.
