Trigger Options

• Usually the TR xx-xxx comes with two 50 Ohm terminated BNC trigger inputs. There are two inputs for working with one detector and alternating signals (for example DIAL). The trigger inputs are electricaly isolated from the transient recorder itself and transmit the pulse by inductive coupling.
• There is also a Laser trigger (Trig-Las) option available, that includes a fast photodiode, that works in the UV (355) nm, we think that option is especially useful for passive Q-switched lasers. This option includes a potentiometer for adjusting the trigger threshold and one can monitor the signal behind the discriminator on the second BNC input. In this case the transient recorder has two BNC inputs as in the standard option and additional connector for the photodiode.
