OPERATING INFORMATION
Press the TIMING key to display the Delay parameter ("Delay: 1.000 µs"). Move the cursor (using the
{ } key) to underline the 1 us decade. Now use the increment key { } to increase the Delay noting that
the incidence of PULSE OUT moves in 1 µs steps. Repeat this with the Width parameter to change the
duration of PULSE OUT.
For quick testing of the module, repeal the above using the module output (an optical detector may be
necessary). Since some modules may have rep rate and width limitations, the specific values above
may have to be modified, but the general procedure is the same.
GPIB and RS-232 Problems
For remote operation from either GPIB or RS-232. the {GPIB/RS-232} key menu must be set to display
"Remote Enabled."
When using the GPIB, make sure that the GPIB cable is properly attached and that the address is
specified correctly. The default address is 6. but may be set between 1 and 30.
The 6040 will respond to remote commands only if the Remote Enable line (REM) is asserted. When
this happens the LCD will display "GPIB Remote Mode," and all keys except LOCAL will be disabled.
The LOCAL key allows the user to return to manual operation (unless the GPIB command LLO has
disabled it).
For the RS-232. again check the cable, but also verify that Baud Rate and Duplex are set
correctly.
