Specifications - Tektronix R Instruction Manual

The Type R Plug-In Unit is a combined
power supply and pulse generator which is used
to measure the high-frequency characteristics
of junction transistors by the pulse-response
method, It is designed to operate with Tektronix
530-, 540-, 550- or 580-Series Oscilloscopes.
When the Type R Unit is used in an oscilloscope
incorporating a delay line, a display may be
obtained which shows delay time, risetime,
storage time and falltime simultaneously. In
addition, operation of a push-button switch
connects a front-panel terminal directly to the
input of the oscilloscope. This connection per-
mits you to observe other waveforms, such
as the input waveform of the transistor under
test.
Pulse Generator
Risetime--less than 5 nanoseconds.
Pulse amplitude--Fixed, calibrated steps of
05, .1, .2, .5, 1, 2, 5 and 10 volts. Adjust-
able between steps.
Pulse recurrence frequency--120 pulses/sec.
Minimum output impedance-Beginning of pulse,
50 ohms. End of pulse, 50 ohms in all
positions of PULSE VOLTS control except
as follows: 2-volt position-50 ohms, 5-volt
position-63 ohms, 10-volt position-116 ohms.
Maximum output impedance--20 k ohms.
Vertical Display
Collector current--.5, 1, 2, 5,
% BJ 10 9 20 , 50
and 100 ma/cm.
