Signals of 50 and 100 MHz, alternate mode,
display of cursors and frequency values.
TV burst signal in delay mode with 2. trigger.
The excellent user interface characteristics of the new
HM404
-2
oscilloscope are
comparable with high tech scopes. Supported by
two microprocessors
any front
panel input is executed in a fraction of a second. A selftest procedure checks all
relevant parameters of the device; the test results will be displayed on screen within
ten seconds after power on. Supported by an
on screen menu
adjustments can be
performed without opening the scope.
It is recommended to use the
Autoset
function if signals of lower complexity shall
be displayed. The scope’s logic circuitry performs all relevant parameter settings
automatically to optimize the presentation of the signal(s). Of course, any parameter
may be modified manually as required. Front panel settings (measurement parameters)
and selected features are alphanumerically displayed on the screen. The cursor
functions enable the user to analyze a signal while watching the numeric readout for
voltage difference, time difference, or frequency values. Another feature is the sto-
rage capability for nine complete parameter settings, which may be stored and recalled
randomly by pushing the according front panel key.
Because of its high performance characteristics of the broad band signal amplifiers
and its excellent trigger bandwidth the scope is capable to
display 100 MHz
signals.
A delayed time base combined with a second trigger circuit makes the
HM404
-2
an
ideal instrument for high-resolution analysis of expanded, asynchronous signals.
Furthermore, the built in component tester and the
1kHz/1MHz calibrator
are standard
equipment for this class of
HAMEG
scopes.
The instrument may be remotely controlled by any personal computer via its built-
in serial interface. A CD-ROM supplied with the scope, contains the instrument
commands and programming examples.
