Chroma 61705 - GPIB Address, RS-232 C

Programmable AC Source 61705 User’s Manual
3-12
THD to 10%. MODE = THD PER = 10.0 %
1. The clipped sine is programmed by “AMPlitude” or “Total Harmonic
Distortion”. Programming ranges from 0 to 100% for amplitude (100%:
no clipped sine), and from 0 to 43% for THD (0%: no distortion).
2. User-defined waveform is defined on a remote PC and downloaded
from it.
3. For detailed of factory DST waveform refer to Appendix B.
1. When using user-defined waveform, if the waveform frequency is over
1000Hz, it might cause the AC Source be damaged.
2. Because of the bandwidth limitation of AC Source, the output may be
distorted. Especially when external V reference consists of high
frequency composition.
3.6.3 GPIB Address, RS-232C
The AC Source offers the mode of remote operation too. Users can set them on CONF
functional list (see 3.6). For details please refer to Chapter 8. Prior to remote operation
users have to set the GPIB address 10 as below:
1. Move the cursor to the command ADDR = 30_
line of GPIB address.
2. Press 1 , 0 , ENTER to set address 10. ADDR = 10
Address ranges from 1 to 30.
The AC Source offers another remote operation through the RS-232C bus. Communication
protocol is set as follows:
To set parity=ODD, baud rate=19200.
1. Move the cursor to the command PARITY= NONE_ BAUD=9600
line of PARITY.
2. Turn the RPG to select ODD, then
press ENTER. PARITY=ODD BAUD=9600_
3. The cursor moves automatically to
the position of “BAUD”. Turn the
RPG to select "19200", then press PARITY=ODD BAUD=19200
ENTER.
The options of baud rate are 9600/19200. The options of parity are
EVEN/ODD/NONE.
