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 which is interfacing with the [[7000 series readout system|readout system]]. The front end is isolated using transformers used for pulses and a floating ±15 V supply. | |||
The Probe jack for the P6058 has contacts for the temperature sensor (a diode-connected transistor) as well as the voltage input terminals. | |||
