Characteristics— Type 535A
or measuring the resistance, capacitance or inductance of
circuit components.
The Type S offers calibrated forward currents in five fixed
steps from 1 to 20 milliamps, and reverse currents calibrated
in six steps from 0 to 2 milliamps. Diode shunt capacitance
is 9 picofarads, and deflection factors are 0.05 v/cm and
0.5 v/cm calibrated.
Type T
The Type T Time-Base Generator provides sawtooth sweep
voltages from 0.2 µsec/div to 2sec/div. The trigger source
may be line frequency, external, ac or dc coupled, auto­
matic or high-frequency sync. The triggering point can be
on either rising or falling slope of the waveform, and trig­
gering level is adjustable. A signal of 0.2 to 50 volts is
required for triggering.
Type Z
The Type Z Plug-In Unit extends the accuracy of oscillo­
scope voltage measurements. It can be used in three modes
of operation: (1) as a conventional preamplifier, (2) as a
differential input preamplifier, or (3) as a calibrated differ­
ential comparator. With sensitivity of 50 mv/cm and in­
sertion voltage range of ±100 volts, the effective scale
range is ±2000 cm. Maximum resolution of the Type Z
Unit is .005%.
As a differential input preamplifier, the Type Z accepts
passband of dc to 10 mc for the 535A for signals that do
not overscan the screen. The deflection factors are 0.05
volts/cm to 25 v/cm in 9 fixed, calibrated steps.
As a differential input preampliifer, the Type Z accepts
a common-mode signal level ±100 volts with input attenua­
tion XI, and offers a common-mode rejection ratio of
40,000 to 1. Maximum input signal is 1 volt/7 nsec, or —1
volt/5 nsec.
As a calibrated differential comparator, the Type Z
makes available three comparison voltage ranges; from
zero to ±1 volt, zero to ±10 volts, zero to ±100 volts.
