The Front Panel Power The LED is on when power is applied to unit and the unit is operating properly. External Reference Signal The LED is on when a 10 MHz reference is applied to the tuning port and the reference select switch is in the 10 MHz position. DC/10 MHz Tuning mode select switch used to change from DC tuning mode to 10 MHz external PLL mode. -

Page 6: Operation
LNFR-100E. The tuning port sensitivity is 0.5 Hz/Volt and the frequency modulation bandwidth is approximately 300 Hz. In the 10 MHz position the LNFR-100E will phase- lock to a 10 MHz signal provided at the tuning port. The external reference signal level must be between +7 dBm and +15 dBm for proper operation. - Page 7 Replace all hermetic covers when done adjusting the frequency of the oscillators. Replace the top cover of the LNFR-100E. Note: The LNFR-100E should be turned on for 1 hour prior to any mechanical frequency adjustment. Copyright © SpectraDynamics, Inc. 2006...
