RC-88 Radio Controlled Clock/Watch Signal Generator

Description:

The RC-88 signal generator can deliver a multi-band signal for reception tests of Radio Controlled Clock’s or watches. The output level can be displayed in μV or dB. All default frequencies can be tuned for frequency shift tests. A back up battery powers the internal clock when AC power is removed. As this unit have a highly sealed cabinet, the carrier signal will have a very small leakage out of the case making it suitable to be used for tests in shielded enclosures. To keep long time accurate of the display clock, RC-88 employs a GPS time receiver which can update the timer clock every minute.
