VHF Frequency Converter. The input is a 10.7MHz frequency
modulated signal at a level of -3dBm. The output is a
modulated signal in Band 11 at a level of +17dBm. Output
frequency is selected by choice of crystal frequency.
Power requirements 12V 100mA. Printed board approximately
l30mm x 105mm. Parent equipment MD3/13. Superseded by
C02/23A. DD 1978. DDMI5.373(79). OBSOLESCENT.
Variable Divider Unit used in GE1/517. Fed from C02/507
at half stable oscillator frequency. Gives normal
division ratio of 891 which can be altered to either 889
or 893 by UN9/52S so that the picture phase of the
waveform from the associated waveform generator can be
brought into approximate sync with another waveform.
Comprises CH1/26 with 10 UN1/535. DD 1961/63. ACO.
Divider Unit used in GE1/517. Input is from OS2/503 and
one output at 1/77 of the oscillator frequency is fed to
the two MD1/50l, and another output at half the oscillator
frequency is fed to the two C02/506. Comprises CH1/26
with 8 UN1/535, 2 AM5/509, AM1/522. DD 1961/63. ACO.
Field Divider Unit used in GE1/517. Input at twice line
frequency from MD1/501 is divided to give rectangular
waveform output at field frequency. Comprises CH1/26 with
