Philips PM 5133 Generator
Function generator 10mHz-2MHz
The PM 5133
is designed for research,
industrial and educational applications and the spezialized
audio service workshop.
The instrument provides both linear and logarithmic sweep
facilities, plus a wide range of other useful facilities in
one self-contained instrument. For example, it offers sine,
square and triangular waveforms, positive or negative pulses
and DC, a variable duty cycle (10 % to 90 %) and a 10 mHz -
2 MHz frequency range selectable via a 7-position rotary
switch having an overriding coarse/fine control. Combined
with the 3 1/2 digit LED display, the fine adjustment
provides an immediate and very accurate readout of sweep
frequency and other setting conditions. Thus setting-up
compared with the usual dialsetting procedure is simplified,
whilst parallax is eliminated.
A maximum output of 20 Vpp (10 Vpp for pulses) is available
at the frontpanel mounted socket. A pushbutton gives choice
of 600 or 50 Ohm output impedance. Output attenuation of
more than 60 dB is selectable in 3— 10—20—30 dB calibrated
steps with a continuous 20 dB overriding control. The 3 1/2-
digit display can be used to monitor the open circuit output
Sweep facilities include single shot and continuous
operation, with the choice between linear and logarithmic
mode. Frequency ranges are divided into seven linear and
five logarithmic subranges with continuous coarse and fine
adjustment. The logarithmic sweep ranges cover more than
four decades, which makes the instrument useful for sweeping
in the audio frequency range.
The single sweep can be triggered either manually, or
electronically from an external source. The sweep period is
continuously adjustable between 5 ms and 100 s. The START
and STOP frequencies can be set independent of each other.
A HOLD facility allows a sweep to be stopped at any desired
frequency, useful for checking phenomena which may appear
during a sweep. An interrupted sweep is continued by
releasing the HOLD button. If required, a sweep can be reset
to the start frequency by means of the RESET button. When
the instrument is used in the sweep mode, the start, stop
and run frequencies are all indicated on separate LED's.
An error-warning lamp automatically lights up, if the
operator selects any incompatible setting.
also offers an internally or externally
controlled burst and single-cycle signal with a continuously
adjustable start/ stop phase between -90° and +90°.
The input/output facilities include a TTL output, a pen-lift
control, an internal modulation voltage and a frequency
The ergonomic design of the instrument ensures ease of use.
It's rugged construction and compact size provides maximum
electrical and mechanical protection.
