3. Verifying RS-232 Functionality
You can use the HyperTerminal program available on your computer to verify the RS-232
interface functionality.
To run the HyperTerminal program, connect the RS-232 cable between the computer and the
signal generator, set the signal generator’s baud rate to 9600, and perform the following steps:
1. On the PC click
Start >Programs > Accessories > HyperTerminal.
2. Select
HyperTerminal.
3. Enter a name for the session in the text box and select an icon.
4. Select COM1 (COM2 can be used if COM1 is unavailable).
5. In the COM1(or COM2, if selected) properties, set the following parameters:
• Bits per second: 9600 must match computer’s baud rate
• Data bits: 8
• Parity: None
• Flow Control: None
NOTE With software flow control the user cannot transmit binary data (file IO).
6. Go to the HyperTerminal window and select
File > Properties
7. Go to Settings > Emulation and select VT100.
8. Go to
Settings > ASCII Setup.
9. Check the first two boxes and leave the other boxes as default values.
Once the connection is established, enter the SCPI command *IDN? in the HyperTerminal
window.
The signal generator should return a string similar to the following, depending on model:
<instrument model name and number>, US37040098 B.03.00
