The Tektronix TM503 is a three-bay mainframe for the TM500 system.

All bays are low-power. It has a single strap carrying handle on the right side.

The TM503A moves the power switch to the rear and has a swiveling carrying handle that can also act as a stand.

The TM503B retains the power switch position and changes the handle material to plastic. It also allows the power supply/backplane part to be removed from the case so that modules to be repaired on the bench without using extenders (see link below). It also has openings for the TM5000 GPIB feature, but not the connectors nor the power good signal for TM5000 plugins.

Key Specifications

  • please add

Option 2

Option 2 adds internal pin headers for each slot as well as rear 50-pin and BNC connectors, allowing for custom wiring to, from and between plugins.

On the standard TM503, cutouts for three BNC sockets have been made in the rear frame, meaning that the user only needs to drill holes in the rear cover plate to install the sockets.

Option 7

Option 7 adds barrier keys (214-1593-02) and connections on the rear interface to allow connections between a DC502 Opt.7 to a TR502 or SW503, such that the center or marker frequency of a sweep can be read of the DC502.
