|Philips PM 5133 Generator|
|Beschreibung:||Function generator 10mHz-2MHz|
The PM 5133 function generator 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 voltage. 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. The generator 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 control voltage. The ergonomic design of the instrument ensures ease of use. It's rugged construction and compact size provides maximum electrical and mechanical protection.
