The PM 5326 RF signal generator has been specially designed for radio and television development laboratories and those involved with receiver sensitivity and selectivity measurements. The generator also provides four sweep ranges for the alignment of IF amplifiers and FM receivers for workshops and education.
Color Coded Controls
The PM 5326 is divided into three functions: main RF oscillator, sweeper, and marker generator. Controls for each function are color-coded, and grouped for operator convenience.
Main RF Oscillator
The output frequency extends from 100 kHz to 125 MHz in 9 push-button selected ranges covering the AM/FM radio spectrum. A built-in 5-digit display enable frequencies to be easily set to 1 part in 10000, essential for precise alignment procedures, selectivity and filter tests.
The output level is electronically stabilized for all ranges eliminating resetting and the need for meter reading and can be continuously attenuated to over 80 dB from the maximum of 50 mV into 75Ω. This may be set to levels calibrated at -3 dB and -40 dB with a separate attenuator. An additional unique feature of the generator is the special attention given to spurious RF radiation. A «double-box» construction gives a high degree of screening, keeping RF radiation very low and ensuring that low level outputs in the region of 0.5 µV can be used with full confidence.
AM/FM Modulation
A choice of CW or MCW output AM or FM and internal or external modulation signals are quickly selected by push-buttons. All AM signals can be internally modulated by a 1 kHz tone to a depth of 30% which is adequate for most applications. This can be increased to 100% over the range 20 Hz to20 kHz (3 dB) by an external source. Frequency modulation may be applied to the 10/11 MHz and 75-110 MHz ranges allowing completer alignment checks to be made on FM receivers. Internal frequency modulation at 1 kHz is equivalent to a 22.5 kHz deviation. External signals can be applied to a maximum deviation of 75 kHz over the frequency range 20 Hz to 60 kHz (3 dB).
A swept frequency oscillator output is available to measure the dynamic response of intermediate frequency amplifiers in AM/FM and TV receivers. Four frequency ranges are selectable by push-buttons. The maximum sweep widths are 50 kHz for AM/IF, 1.2 MHz for FM/IF and Band II and up to 10 MHz for the video IF ranges. Sweep rate is either by a linear sawtooth between 3-30 Hz or at a line frequency sinewave with phase adjustment.
Marker Generator
Markers are available in each RF sweep range to indicate a precise frequency scale over the complete spectrum. The position of the variable marker is controlled by the main frequency control and the setting is displayed on the internal counter. Fixed markers at regular intervals may be added to the output signal by pulling the marker amplitude switch.
