NFORMATION
The MOD745 device provides four high precision independent delay channels. Access to these four
outputs (T1-T4) is given by four BNC connectors on the front panel. The achieved delay resolution
is about 0.25ps, and trigger-to-channel jitter is less than 25ps (
). T1-T4 can deliver up to
5V, 2ns rise time max (
), into 50Ω. Amplitude and width are adjustable on each output
channel either programmed from the front panel or via Ethernet.
A T0 output pulse is also available. It gives a time reference for each generated delayed output.
This high accuracy and precision device is suitable for system/experiment in science or industry
that requires reliable timing solution.
The MOD745 also provides four optional delay channels to rear panel T5 to T8 with also a delay
resolution of 1.25ns, trigger-to-channel jitter less than 50ps with a common 2 to 5V tunable
amplitude.
The internal timebase reference is a TCXO with a stability of 0.5ppm. An optional OCXO with a
50ppb precision can replace the standard one.
The device offers three operating trigger modes, repetitive (internal or external source), single
shot (internal, external or asynchronous source) and a burst mode (internal, external or
asynchronous source).
A Web page (accessed via Ethernet link) provides a simple method to configure the settings for
each channel, amplitude, width, trigger source, trigger mode and to control operation. You can
save and recall settings.
