The '''Tektronix 132''' is an external enclosure, power supply, and amplifier for a [[Letter-series_and_1-series_plug-ins|letter-series or 1-series plug-in]]. | |||
It was [[introduced in 1961]]. | |||
The 132 supplies power to the plug-in, and amplifies the signal output of the plug-in (i.e., at pins 1 and 3 of the plug-in's rear connector) through a three-stage DC-to-16 MHz all-tube differential amplifier. | |||

==Internals== | |||
The resulting vertical signal is available on the front panel of the 132 either using [[UHF connector]]s (early 132 versions) or [[BNC connector]]s (late 132 versions). | |||
The 132's power supply is similar to Tektronix oscilloscopes of the late 1950s and early 1960s, | |||
with solid state rectifier diodes, and tubes as regulators. | |||
An [[OG3]] tube is used to generate a −150 V reference voltage that is used for all of the other regulated voltages. | |||
The +225 V and +350 V supplies are floating supplies stacked on top of the +189 V unregulated DC that feeds the +100 V supply. | |||
The 132 has a fan that is always on when the power is on, and a 58°C (137°F) [[thermal cutoff]] for the rest of the circuitry. | |||
The differential front panel output of the 132 has an output impedance of about 5 kΩ per side. | |||
The gain and bandwidth of the entire system (plug-in + 132 + load) depend on the load impedance. | |||
For exact gain, the 132 needs to be terminated with an exact impedance. | |||
A load impedance of 93 Ω maximizes bandwidth, further reductions of load impedance only reduce the available output swing. | |||
A load impedance of 50 kΩ maximizes gain, further increases in load impedance have little effect on system performance. | |||
