The Tektronix 7623 is a 60 MHz analog multi-mode storage mainframe, introduced in 1973.
The 7623A facelift in 1975 increased bandwidth to 100 MHz. The 7623B version, specified at 100 MHz, added a reduced scan mode to increase stored writing speed. It replaced the 7613, 7623A and 7633 in 1991. There were also R7623(A,B) rack-mount versions.

Key Specifications

	— 7623 —
Bandwidth	tba
	— 7623A —
Bandwidth	100 MHz with 7A11, 7A16, 7A19, 7A24, 7A26; 75 MHz with 7A13, 7A18
Fastest cal. sweep	5 ns/Div
Stored writing speed	fast var persist - 150 Div/μs, fast bistable - 50 Div/μs, var persist - 0.5 Div/μs, bistable - 0.03 Div/μs
CRT	T7411, 8 x 10 Div. @ 0.9 cm, P31 phosphor, 8.5 kV acceleration
	— 7623B —
Bandwidth	tba
Stored writing speed	1000 cm/μs (in reduced-scan mode)
	— Common —
Calibrator	40 mV, 400 mV or 4V into 1 MΩ, 1 kHz
Storage modes	variable persistence, fast variable persistence, bistable, fast bistable, non-store
Weight	13.6 kg (30 lb)

Internals

The 7623 uses a Transfer storage CRT which includes an internal, fast-responding storage mesh. In fast mode, the time base is inhibited after a sweep, and the transfer cycle is started. Individual sweeps therefore occur in about one-second intervals.
