The requirements of modern service and industrial applications can
easily be met with
HAMEG’s HM304
microprocessor
controlled
oscilloscope. The new
"AUTO SET"
capability allows for automatic setup,
where the user need only adjust the focus and intensity controls. All other
settings instantaneously and automatically configure in response to the
input signals when "AUTO SET" is active. The instrument’s intelligence
modifies only those parameters that are necessary for proper signal
presentation. This mode typically generates a display with a period of three
signal repetitions, that has an amplitude of approximately six divisions for
single channel and half of that for dual channel operation. Manual control is
also possible for all settings. A
PC’s serial port
can control remote
operation via the
RS-232
serial interface.
LED’s
indicate measurement
range settings and functions.
A memory base that can store six different customer-defined control
scenarios facilitates repeat measurement tasks. User settings can be
saved and recalled without restriction.
The two vertical (Y) channel amplifier’s
35MHz
bandwidth display
signals over
100MHz
. High frequency trigger circuitry permits synchronization
to signals (having 0.5 division amplitude) beyond 100MHz. The high
resolution timebase allows signal expansion in the 'delay' and 'automatic
trigger after delay' modes by a factor of up to 1,000 times. The HM304 is
equipped with a built-in
Component Tester
, dual frequency (1 kHz / 1 MHz)
calibration signals and mu-metal CRT shielding. A switching mode power
supply saves both energy and weight with the complete unit weighing only
5.5 kg. (12.1 pounds).
This unit offers attributes, only too easy to get used to, that are beyond
compare to other instruments in this price range. Expert users will rapidly
identify that the HM304’s deluxe suite of features shall be the standard for
future high performance oscilloscopes.
