Tektronix T932 Dual Trace 2 Channel Analog Oscilloscope in Working Excellent Condition Both Operational and Cosmetic. Also comes with carry case made of wood. Scope has feet for both horizontal and vertical use. The T900 Series was introduced in 1975, first appearing in the 1976 Tektronix catalog. The line included the 10 MHz single channel storage T912, the 15 MHz single channel T921, the 15 MHz dual channel T922, the 35 MHz T932, and the 35 MHz delayed sweep T935 models (the T932A and T935A were 1978 updates). The T922R was the only rack mount oscilloscope in the T900 Series (the R suffix indicates rack mount). The T922R was also designated as the OS-287/F by the military, and an official looking military name plate is sometimes seen on the front or back of scopes acquired as military surplus. The T922R was introductory priced at about $1,220.00 in 1976, and was priced at $2,095.00 in the last catalog in which it appeared in 1984. The rarely seen Option 1 added a fourth vertical mode pushbutton (labeled DIFF) which, when pressed in alone, inverts the Channel 2 signal and displays the sum of both channels (it has other functions when used in concert with other mode buttons). Earlier production T922Rs have a neon power indicator pilot lamp, while later production models have an LED indicator. The T922R was last produced in 1984 (but may have been sold as late as 1988 or 1989), and long term support from Tektronix was ended in 1995. Tektronix no longer stocks parts unique to the T900 Series, and has farmed out "best effort" support to Verizon (GTE). (We do not proofread any ads submitted by members) |
