PULSE DISTRIBUTION AMPLIFIER
The PD-15RMi series is a TTL Pulse Distribution Amplifier that provides distribution for one pulse per second (PPS) signals. The amplifier may also be used to distribute pulses with a repetition rate of up to 100 MHz. The outputs provide a 4.3 volt peak-to-peak signal into a 50 ohm load. The channel-to-channel delay differences are typically less than 100 ps. The distribution modules have typically 3 ps/ºC temperature coefficient of propagation delay. The small propagation delay characteristics and low temperature coefficient of delay are essential for the distribution of high quality timing signals. This instrument is designed to be powered by a 100 to 240 VAC mains source or by a +12 to +36 VDC power source.
