Nagra qfms pilot frequency meter kudelski iv-s instructionsNAGRA KUDELSKI G ‘ QFMS Pilot Frequency-meter Plug-in Module for NAGRA IV-SThe QFMS is a plug-in accessory for the Nagra lV-S and is designed to measure the pilot signal frequency, and thus the camera speed. The frequency is indicated on the Nagra meter, and allows the operator to check whether the pilot signal is within the frequency range necess- ary for a good synchronization. The scale indicates + 4 % to - 4 96, and the precision at the centre of the scale is within i 0.1 96. The zero stability is obtained by means of a mica condenser and several very high stability resistors. The makers of these components indic- ate that the stability of the com- bination is 120 ppm. The zero may be checked by means of a QGX quartz crystal controlled pilot generator. In addition. the frequency meter gives an alarm signal if the frequen- cy deviates by more than 5 96 from its nominal value. and the pilot indicator of the Nagra lV-S turns black. The QFMS exists in two ver- sions for 50 Hz and 60 Hz: QFMS 50 and OFMS 60 respectively.
