Kennzeichnungen und Vorschriften nach DIN EN 60825-1 gekennzeichnet.
Fig. 1 Identification label at the device
RoHS statement
The device and all components comply with RoHS Directive 2011/65/EU (RoHS).
WEEE-sign (ElektroG) - Waste of Electrical and Electronic Equipment.
The device is labelled with the symbol
2.4 Intended use
The device is intended for driving of a RF-Driver with acusto-optical modulators (AOM). The RF-Driver must be
provided with inputs for the TTL-Signal (input low impedance 50 Ω or up to 10k Ωhigh impedance).
The device use FC-Fibre connector as Trigger –input for the pulses. For this a fibre coupler can be used which
guides a part of the output light (5 - 10 %) to input. Since an InGaAs-photodiode is built in the wavelength can
be between 1000 nm and 1700 nm.
Please store the manual near to the device and accessible for all users.
Furthermore, please take care that all necessary documents like laser safety regulations or country-
specific safety regulations are present.

3.2 AOM-output (SMA)
Output
Connector: SMA(f)
Voltage: TTL (square wave)
Current: ± 100 mA
TRise / TFall: < 1.5 ns
A driver for acusto-optical modulator (AOM) needs typical TTL voltage pulses for switching between the off
and on states. The exact value is given in the data sheet of the AOM –Driver.
The AOM-output is optimized for an output impedance of 50 Ω. Shortening the output may lead to
irreparable device damage.
The AOM-output is optimized for an output impedance of 50 Ω. For other output impedance values
the voltages are not correct.
3.3 AOM-MONITOR (OUTPUT)
Output
Connector: SMA(f)
Voltage: TTL (square wave)
Current: ± 100 mA
TRise / TFall: < 1.5 ns

For monitoring the AOM Driver Signal is duplicated on this port.
The AOM-Monitor output is optimized for an output impedance of 50 Ω. Shortening the output may
lead to irreparable device damage.
The AOM-Monitor output is optimized for an output impedance of 50 Ω. For other output
impedance values the voltages are not correct.
3.4 GATE-INPUT
Input
Connector: SMA(f)
Voltage: TTL/LVTTL
Frequency: < 100 MHz
Input impedance: 50 Ω
Minimum pulse width: 100 ns
The GATE-INPUT provide a logical AND-Function for the AOM-OUTPUT.
Truth table:
Input
HIGH AOM –OUTPUT DIVIDED PULSES
LOW AOM - OUTPUT BLOCKED
3.5 PHOTODIODE INPUT (TRIGGER-IN)
Input (optical)
Connector: FC (f)
Input Power: max. 10mW (cw)
Pulse Repetition Rate: max. 200 MHz
An optical pulse at the Trigger input increases a counter until a software pre-set value is reached. Then a TTL-
pulse is emitted at the AOM-output. The AOM-output pulse will have the pulse width and delay which was
pre-set using the software. The counter will be set back and counts again following the next Trigger input
pulses.
3.6 PHOTODIODE MONITOR OUTPUT
Output
Connector: SMA(f)
Voltage: Pulses < 2Vpp
Current: ± 100 mA
TRise / TFall: < 1.5 ns
