Philips PM 5134 Gerador
The PM 5134
is an easy-to-use yet sophisticated function
embodying a wide range of facilities in a single
It produces sine, square and triangle wave forms as well as
positive or negative pulses and DC. The duty cycle is
variable between 10% and 90%.
The 1mHz to 20MHz frequency range is selected by means of a
10-position rotary switch with an overriding coarse/fine
adjustment. This fine adjustment, combined with the 3 1/2
digit LED display, gives an immediate, highly accurate
readout of the selected frequency.
Setting up procedures are thus very much simplified compared
with the traditional dial setting and any human errors (e.g.
paralax) are eliminated.
In addition, the 3 1/2 digit display can be used to monitor
the open-circuit output voltage. Also, when used in the
sweep mode, the start, stop and run frequencies are
indicated by separate LEDs. Moreover, an error warning lamp
automatically indicates any incompatible setting-up conditions.
The high , nominal accuracy of ±2% ±1 digit, can be further
improved to ±5 x 10 by operating the instrument in the
crystal-control mode. This facility is useful, for example,
for identical repetitive measurements requiring high
accuracy, or for narrow band Filter
tests. The X—TAL AM mode
offers a stable carrier wave with defined frequency. One
particular application is when using a 10.7 MHz carrier
frequency to check that the discriminator section of a radio
receiver is suppressing the AM wave form.
The continuously variable 20Vpp max output (10Vpp for
pulses) is available at the front panel socket; there is a
pushbutton choice of 600Ω or 50Ω output impedance. The
output attenuation is selectable in any combination of
3-6-10-20dB pushbuttons with an overriding continuous 20dB
Sweep facilities include single and continuous operation.
The single sweep can be triggered either manually, or
electronically from an external source. The sweep period is
continuously adjustable between 5ms and 100s. The START and
STOP frequencies are non-interactive and can be set
independently of each other. A HOLD facility allows a sweep
to be stopped at any desired frequency — useful for checking
phenomena occurring during a sweep — by means of a
pushbutton. An interrupted sweep is continued by simply
releasing the HOLD button. If required a sweep can be reset
to the start frequency using the RESET pushbutton.
offers an internally or externally controlled
burst or single-cycle signal. The start/stop phase is
continuously adjustable between -90° and +90°.
The internal AM is adjustable between 0 and 100% modulation
depth. The modulation frequency can be set over a wide range
from 10mHz to 20kHz. The AM facility can be used with
crystal control, if desired. External AM inputs in the range
from DC to 20kHz can be applied via a rear-mounted BNC- socket.
The internal FM can be continuously adjusted between zero
and ±10% frequency deviation.
Other input/output facilities available on the rear panel
include a TTL output and pen lift control.
The design of the PM 5134
has resulted in a clean, simple
front panel layout which allows the operator to become
quickly familiar with all control functions. Its overall
versatility makes it suitable for a wide range of
applications within research, design or educational
organisations. The instrument occupies minimal bench space.
