The
HM6042 Curve Tracer
is used to accurately display the characteristics of two and three terminal
semiconductor devices. The instrument combines ease of operation and versatile features at an
affordable price. Unlike its counterpart, the HM8042 plug-in unit, it uses a built-in
CRT
and an
LCD
to
display the characteristics of the device under test.
The
HM6042
displays a set of 5 curves at a time. All numeric values and parametric data can be
read out on a 2x16 digit
LCD
. Device type and all relevant parameters are selected and modified by a
simple front-panel keypad entry. Collector voltage and current parameters are easily changed. A 3-
step power limiter avoids damage of the
D
evice
U
nder
T
est
by excessive power.
One set of parameters can be stored in memory for comparison of one device to another or a
reference device. This feature gives substantial enhancements in productivity when matching
semiconductors. Two cursors can be moved along the displayed curves. X and Y position of the cursor
will be displayed on the screen. Basic accuracy is 2% of the measurement value. Measured parameters
are: base voltage, base current, collector current, collector voltage and Beta. The dynamic parameters
h11, h21, and h22 are
calculated
by the
internal processor
.
A device adapter socket with side-by-side terminals for two devices for the comparison of two
semiconductors is supplied with the instrument.
The
HM6042
is remarkably easy to operate. This makes the instrument also ideally suited for
educational use.

Cursor Measurements:
Single mode:
The Cursor marks the position from which the
measurement value is calculated.
Tracking mode:
Two Cursors mark the positions, from hich
the h/y-Parameter measurement values are calculated.
