The Tektronix SA501 is a signature analyzer plug-in for the TM500 system.

It is also known as the 067-1090-00.

It requires a P6405 probe for the data input, and a P6458 4-channel probe for control inputs (clock, start, stop, qualifier). The P6458 can be substituted by the similar, more common P6451 8+1 channel probe without increase in functionality.

Key Specifications

Data Input	1 MΩ to ground or 50 kΩ to 1.4 V, switchable; 14 pF; max. 40 V DC+peak AC
Threshold	fixed TTL, internal preset, or variable ±12 V
Data rate	40 MHz max.; 15 ns setup time, 0 ns hold time
CRC polynomial	x¹⁶+x¹²+x⁹+x⁷+1
Display	4-digit modified hexadecimal (0-9,A,C,F,H,P,U)

Patent US 3976864A	Apparatus and method for testing digital circuits	Gary B. Gordon • George A. Haag • Jan R. Hofland • Daniel I. Kolody	1974-09-03	1976-08-24	Signature analysis • 308 • SA501

Internals

The SA501 is implemented in standard ECL and TTL logic without a microprocessor. A linear-feedback shift register accumulates the CRC. The display is multiplexed, with an IM5610 32×8 PROM used as a 7-segment decoder.

The SA501 contains a switch-mode converter fed off the +33.5 V supply to create the internal +5 V rail.

The manual includes signatures for troubleshooting a SA501 with another signature analyzer.
