Datasheet

5.2 TTL Pulse Generator (TPG)

5.2.2. Setting the pulse parameters

1. remove the TPG from the Starter Kit and connect it to the mains independently

2. set the TPG mode to internal

3. connect the TPG to a scope using the Output BNC cable: a 5V TTL signal

should be displayed

4. set the pulse parameters as speciﬁed in the datasheet (see section 4.2):

a) set the pulse duration to 50 ns using the 0-200 ns knob (4)

b) set the pulse period to 2.5 µs using the period knob (2) and toggle switch

(3)

5. once the testing conditions are retrieved, set the pulse parameters as desired,

but within a reasonable range of the parameters speciﬁed in the datasheet.

Note: the pulse duration should be kept long enough to not distort the TTL

signal.

6. lock the knobs (2) and (4)

7. turn off the TPG and disconnect it from the mains

IMPORTANT:

The operating parameters are speciﬁed in the datasheet provided with each laser;

any operation outside the speciﬁed range must be agreed with ALPES LASERS or

may result in the loss of warranty.
