The Technique
The excellent frequency response of
the signal amplifiers and the stable triggering abilities from only 5mm peak-topeak on the screen, enable the scope to
display sine waves far beyond its -3dB
frequency without any problems. With
rectangular signals the instrument‘s own
overshoot is less than 1%. The instrument
contains a second trigger system to ensure
stable triggering of even asynchronous
signal components. With its second time
base, the HM1507-3 scope is capable of
displaying not only the signal itself but also
a freely selectable expanded section in
mixed mode, according to the time base
and trigger delay settings. This function is
available in both analog and digital modes.
In contrast to analog operation there is no
intensity reduction in digital mode, even if
high expansion ratios are chosen. Low noise
8 bit flash converters are used to digitize
the signals to be analyzed. A so called dot
join function linearly connects successive
points to display curves without any gap.
The scope digitize and store any signal with
more than 2000 samples per sweep. The
well proven CRT is suitable to reproduce
signals in this high horizontal resolution.
200MS/s allows a clear display of single
shot (real time) events up to frequencies
of 20MHz. To display variations of a signal
over several samples it is recommended
to use the envelope or the average mode.
Another important feature is the pre/post
trigger function that enables the user to
analyze signal components that occur
before/after the trigger event. Two fullsize reference memories allow the comparison of signals with those already
stored in memory. The HM1507-3 features a peak-detect function which allows
the automatic capture and storage of non
repetetive signals. Signals down to 5ns
wide can be detected at timebase settings
up to 5 µs/div.
When the Autoset function is enabled, all relevant parameter settings are
performed by the scope’s circuitry automatically. The Setup parameters and the
measured values are clearly displayed on
the screen in alphanumeric characters.
Autoset also initiates automatic cursor
settings for time and frequency measurement (digital only) as well as voltage
measurement. In analog and digital mode,
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 storage capability for nine
complete parameter set ups, which may
be stored and recalled simply by pressing
the appropriate front panel key. A remarkable feature of the scope is the built-in
calibrator - a 1kHz/1MHz square wave
generator. It allows frequent checking
of the instrument’s frequency response -

from the probe tip to the display on the
screen. It also permits high frequency
alignment of the probes. Supported by a
Built-in calibrate menu, closed-case adjustment procedures of the vertical-, triggerand storage amplifiers are possible.
With all of the new HAMEG scope
range, microprocessors manage the front
panel inputs, calculations, and other control functions. In addition, 32 bit RISC
processors accelerate the digital signal
processing. The instrument may be remotely controlled by any personal computer via its built-in serial interface in all
relevant functions. A suitable software program is supplied with the scope on delivery.
Operation
Like all members of the new series of
HAMEG oscilloscopes the HM1507-3
combines a wide range of useful functions with an easy to use operator interface. The logically designed layout and
the proven functionality of the keys and
knobs make additional menu keys avoidable. Even inexperienced oscilloscope users will soon become familiar with these
instruments.
The easiest way to display signals of
low complexity is the use of the Autoset
function. The scope’s logic circuitry performs all relevant parameter settings automatically for the best readout of the signal on the screen. The set up parameters
and the result of the selected measurement function are clearly displayed on the
screen. Another feature is the storage
capability for nine complete parameter

settings, which may be stored and
recalled randomly by pushing the relevant front panel key. It includes beam
intensity and cursor parameters settings.
The cursor functions enable the user
to analyze a signal while watching the
numeric readout for the voltage difference, time difference, or frequency.

Calculation Routines
The screen photo shows a composite
video signal with burst. The two time
bases of the HM1507-3 are operating in
the mixed mode. Since the burst is asynchronous to other components of the TV
signal, a second trigger circuit is required.
It can display the signal and the burst
concurrently in two curves.
When signals are displayed in the envelope mode, the influence of jitter effects and amplitude changes can be
demonstrated significantly. The scope
builds the envelope curve by storing the
minimum and maximum values over a
number of consecutive sampling periods.
For ease of operation the envelope curve
can be stored in one of the reference
memories and be displayed in combination with a currently measured signal.
