Information
HM 1005
The 100 MHz Standard for professionals
The HM 1005 is a multi-function Oscilloscope loaded with
features such as true 3-channel operation, a genuine second
time base, and even a separate second trigger facility. Up
to 6 traces can be displayed for evaluating waveform
relationships by using the alternating time base mode and
all three input channels. In this configuration, the normal
signal is displayed together with the expanded signal
section. The second trigger facility, with its own separate
slope and level control, provides for the stable viewing of
normally troublesome asynchronous signal components. The
main time base trigger circuit is designed to provide
reliable triggering to greater than 130 MHz, at signal
levels as low as 1 division. A user-selectable x10 magnifier
extends the maximum sweep range to 5 ns/division. An active
TV Sync Separator extracts clean field and line sync, pulses
to ensure a high degree of display stability when viewing
composite video signals.
The built-in delay line permits viewing of the trigger edge
at all times. The overscan feature indicates if any part of
the trace passes beyond the vertical limits of the CRT
screen. An analog Y-output, switchable to Channel I or II,
allows further external processing of the signal. Another
new feature on the HM 1005 is the easy-to-read 3-digit LED
delay time multiplier for accurate measurements.
As is the case with several Hameg Oscilloscope the HM 1005 also has a built-in switchable 1 kHz /1 MHz Calibrator with
a sharp <5 ns risetime output. This feature is necessary in
high bandwidth Oscilloscope o that the Probe can be
correctly matched and compensated to ensure faithful
reproduction of the input signals. This is especially true
when viewing pulses and other high frequency signals. The Calibrator is also useful for performing checks of the
instrument's transient response characteristics from Probe tip to CRT screen
The HM1005 offers the right combination of triggering
control, frequency response and time base versatility, to
facilitate measurements in every environment from the
laboratory to field service. It is yet another example of
HAMEG's dedication to engineering excellence.
