The Tektronix 7D13 is a digital multimeter plug-in for 7000-series scopes with CRT readout. It will function in any compartment. The 7D13 was introduced in 1971 and followed by the 7D13A in 1982, which has recessed banana sockets on the front panel and is compatible with a different temperature-only probe.
There is no analog output signal presented on the CRT, therefore it is not necessary to select the 7D13 with the oscilloscope Vertical or Horizontal Mode switches.
The input section is galvanically isolated, allowing the input to float ±1500 volts with respect to chassis ground.

Internals
The 7D13 consists of an analog pulse-width modulator front-end, built with 741 op amps and dual FETs, and a 3½ digit counter section, using standard 74xx TTL parts, that interfaces with the readout system through a 155-0038-00 D/A converter. The front-end is isolated by transformers used for pulses and a floating ±15 V supply. The Probe jack for the P6058 (a 4-pin LEMO S-series connector) has contacts for the temperature sensor (a diode-connected transistor) as well as the voltage input terminals.
