Before sending commands
Whether you use RS-232 or GPIB as the communication interface to the 2411B, you should examine the
following.
For RS-232
1. Check the cable connection.
Make sure the proper end (
PC or Instrument ) of the cable specified by TEGAM is connected to the
respective ends.
PC to PC COM port
Instrument to 2411B RS-232 connector
2. Setup the PC Port.
Select a COM port on the PC. Make sure that the baud rate and other interface parameters are set to the
same parameters as the 2411B.
For GPIB
1. Check the cable connection.
2. Set up the GPIB board on the PC to a proper setting.
3. Make sure that the GPIB address set on the PC matches the 2411B address.
Command Features
The following examples will illustrate the specific features of the 2411B remote programming com-
mands using RS-232 or GPIB.
Command Execution
All commands are executed after the execute command (EXEC) is sent .
The only exception is the waveform command ( WVFM ). It does not require the execute command
( EXEC ). You do not have to send commands in any particular sequence. For example, if you want to
change DC offset value and amplitude, you do not have to send and execute the smaller value of
amplitude first.
In general the following formula applies.
| Voffset | + Vpp/2 < Vmax
If the output is set to 10.0V and the DC offset is zero and you want to change to the amplitude to 1.0 V
and the DC offset to 7.5V,
AMPL 1.0;OFFSET 7.5;:EXEC --- OK
OFFSET 7.5;AMPL 1.0;:EXEC --- OK
