Tektronix TM 503 User Manual

Operating Instructions—TM 503
voltage range settings. Actual power consumed, of course,
depends on the particular module combination selected at
any one time.
This power capability can best be utilized by carefully
planning the functional combinations of plug-ins, their
external joads, and the resulting power distributions.
Optimum conditions would be (1} equal loads in all three
compartments, {2} as much power as possible dissipated in
external loads, and (3) operating in an ambient temperature
around +25°C.
The TM 503 provides each plug-in module with access to
a pair of heat-sinked, chassis-mounted transistors, one NPN
and one PNP. These Series-Pass transistors allow the plug-in
modules to operate in power ranges not possible if the
power had to be dissipated in the modules themselves.
