If the buffer cannot store the amount of data requested or if the printer is not ready, the 56100A indicates an error by setting bit 2 of extended status byte and sending a SRQ (if enabled). Bit 0 of the Extended Status Byte indicates that a print is in progress. The printer is connected to the rear panel PARALLEL PRINTER INTERFACE connector.

When a SRQ is generated, the GPIB SRQ control line is set true (low) and the Primary Status Byte is returned to the controller on the GPIB data lines, DIO 1 thru DIO 8.

  • Page 116 If the SRQ function has been enabled and the external controller has been set to respond to them, a controller response to a SRQ from the 56100A will clear the status byte. Therefore, there is no point in using OSB (or CSB) if SRQ’s are enabled.

    OSB == OPB Output Identify Returns identity string to controller, which includes model number and software version number. Output format is: “56100A, nn.nn", where "n" designates software version number Total string length is 12 characters. (Version field is padded with spaces.) OPM(X) Output Parameter X Returns parameter X to the controller.

(Refer to the Cursor Control Commands in Table 5-6.) OCF (N) Output Cursor Frequency Returns the frequency at the current cursor position for display channel (N).

  • Page 124 If the controller is expecting Binary data to be returned (OBT, OCD, OTM, etc), and an error condition is detected and reported by the 56100A, the controller’s received message buffer may be expected to include the (error) ASCII string termination characters (0Dh,0Ah).
  • Page 125 The 56100A must be put in the HOLD mode (using the HON command) before receipt of the LBT command; otherwise, the restored (learned) data will be overwritten with new data. Use care when manipulating this data as it is in minimal binary form; the 56100A is therefore unable to check it for errors or inconsistencies.

It is possible to correctly establish any front panel setup operation by first setting it (using appropriate GPIB commands), then outputting the complete stored setup.
