phase mode, respectively.
2.1.7 System Specification
External Modulation:
0 to 10%
Synchronization Input:
Isolated TTL input for external frequency control. Requires 5V at 5 mA for logic high.
Trigger Input:
External trigger source input. Requires TTL level input signal. Triggers on negative edge. Response
time 80 - 100 µs.
Trigger Output:
Programmable through transient list system. 400 µs pulse for voltage or frequency change. Isolated
TTL output. Output reverts to Function strobe when not uses as Trig Out. This function is mutually
exclusive with the Function Strobe output.
Function Strobe:
Active for any voltage or frequency program change. 400 µs pulse for voltage or frequency change.
Isolated TTL output. This function is mutually exclusive with the Trigger Output. Same output is used
for Trigger Output if Trigger Output is programmed as part of list system.
Output Status:
Mo n itors state of the output relay. Isolated TTL output. High if output relay is closed, low if output relay
is open.
Non vol a t il e memory st orage:
Series I: 8 complete instrument setups and transient lists, 32 events per list.
Series II: 16 complete instrument setups and transient lists, 100 events per list.
