The PTS50 can be used to synchronize up to six instruments to a 5 MHz or 10 MHz reference input. AGC control means a 10 MHz input can be varied from - 10 dBm to + 20 dBm without the output amplitude changing by more than 0.4 dB. The pure sinewave output means that the PTS50 will work in the most demanding applications. Harmonics are at least –70 dBc. A squarewave output can be switched in frequency to 10 MHz, 5 MHz, 2 MHz, 1 MHz, 100 kHz and 1 Hz. This output is ideal for instruments that do not use a 10 MHz timebase. A rear slave output can be connected to a second or multiple PTS50’s for up to 12 outputs or more. A dual colored LED on the front panel shines Red when power (either AC or DC) is applied to the unit and Green when both power and a valid input signal is applied.
