6.6 Remote Control Commands

The diagram below gives the front panel keys and their associated ASCII codes. Sending these characters to the 4070A has the same effect as pressing the associated button on the front panel.

NOTE: To familiarize yourself with the remote operation of the 4070A, it is helpful to run a terminal program on your PC and manually type the commands and watch the response. To get a help menu, press H. See section 6.3 for details. Characters are case insensitive

Figure 6.6-1: Front panel keys to ASCII command mapping

NOTE: Turning the rotary knob clockwise has the same effect as pressing the é key multiple times. Turning the rotary knob Counter-clockwise has the same effect as pressing the ê key multiple times. In addition to the above ASCII command characters, extra commands are available for remote control operation.

They are:

A- Reset the unit to Sine wave mode

V- Report hardware and software versions

K1,0 - Enable, Disable front panel keys and knob

E1,0 - Enable, Disable LCD echo to terminal

F0-9 - Move cursor to field 0 to 9 ? or H - Print help menu

^E - Returns ^C

Each of these "extra" remote control commands is discussed below:

A - Reset 4070A to Sine wave mode

This command resets the 4070A to the Sine wave mode and turns the cursor off. The output-offset voltage is set to 0.0V. When writing control software for the 4070A, it is a good idea to issue this command first so that the 4070A is in a known state before further commands are issued.

NOTE: The frequency and level values are not reset. They are set to the values that existed the last time the unit was in Sine wave mode. (Or the power-up default values if they hadn't been changed). The RS-232 baud rate remains unchanged.
