The Tektronix S-52 is a pulse generator head compatible with S-series sampling units like the 3S2, 7S11, and 7S12.

It puts out a 200 mV pulse into a load of 50 Ω. The pulse has a rise time of 25 ps or less. The output is an SMA connector.

In addition to the main pulse output, the S-52 also produces a pre-trigger pulse 85 ns before the main pulse. The delay is generated with a digital counter, and jitter between the pre-trigger pulse and the main pulse is specified as less than 10 ps. The pre-trigger pulse uses a BSM connector.

Key Specifications

Rise time < 25 ps
Output amplitude 200 mV into 50 Ω (SMA)
Pulse Duration > 350 ns
Output impedance 50 Ω «reverse terminated» (i.e. having controlled source impedance)
Pre-trigger output 85 ns before main pulse (jitter < 10 ps), +1 V into 50 Ω (BSM)

Internals

The S-52 generates the main output pulse using a 50 mA low-capacitance tunnel diode with part number 153-0040-00.

The S-52 is similar to the S-50, but the S-50 has twice the pulse amplitude. The reason for this is that the S-52 has a 48 Ω resistor between the output tunnel diode and the output connector providing back termination, while the S-50 has no such resistor. Although the S-52 produces a smaller pulse, its output impedance is much better controlled than that of the S-50, and the output resistor may also provide some limited protection for the output tunnel diode.

The S-52 uses a 156-0048-00 (LM3046) transistor array in the timing board.
