2) You will get about 2V from GCV output BNC connector.
Note: It won’t make any change on execution and result by taking different step
sequence.
6.18 THE TTL Signal Output Function
The GFG-3015 provides a compatible TTL level signal from TTL Output BNC
connector. The frequency of TTL signal output depends on the main output
frequency. If need to modify the frequency of the signal, please refer to the
procedure of 6.3 The Setup of Frequency.
The amplitude of the signal is fixed at ≧3Vpp which can not be changed.
Example of the Setup of TTL Output
To set the following conditions:
Main Frequency: 5kHz. Signal Type: TTL Level.
Procedure:
Set the main frequency to 5kHz(refer to 6.3 The Setup of Frequency).
Connect with “
TTL output BNC connector”.
You will get a 5kHz/TTL Level signal from the connector.
6.19 THE SYNC Signal Output Function
The GFG-3015 provides a synchronous signal with main output from SYNC
Output BNC connector. The frequency of SYNC signal output synchronizes with
main output. If need to modify the frequency of the signal, please refer to the
procedure of 6.3 The Setup of Frequency.
The amplitude of the signal is fixed at >1Vp-p open circuit which can not be
changed.
Example of the Setup of Sync Output
To set the following conditions:
Main Frequency: 10kHz. Signal Type: Synchronize with main output.
Procedure:
Set the main frequency to 10kHz(refer to 6.3 The Setup of Frequency).
Connect with “
SYNC output BNC connector”.
You will get a 10kHz signal synchronized with main output from the
connector.
6.20 Remote Control - RS232 Interface
The GFG3015 contains a DB 9-pin, male RS-232 connector for serial
communication with a computer or terminal. The GFG-3015’s RS-232 interface
is configured as an RS-232 “Data Terminal Equipment” so that data is sent from
pin 3 and received on pin 2. For remote controls, the RS-232 interface has to be
connected with a computer or terminal.
