 It was [[introduced in 1961]].
-The 132 supplies power to the plug-in and the signal output of the plug-in (i.e., at pins 1 and 3 of the plug-in's rear connector) is amplified by the three-stage DC-to-16 MHz all-tube differential amplifier in the 132.

 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.

 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 and further reductions of load impedance only reduce the available output swing.

-A load impedance of 50 kΩ maximizes gain and further increases in load impedance have little effect on system performance.
