    Operator’s Checks Operating Information Operator’s Checks The operator’s check for the Keysight E1418A has two parts. The first part consists of sending the SYStem:ERRor? query to the module following power-on and entering the response. This check should be performed after every power-on sequence. At power-on, the Keysight E1418A performs a brief self-test that ensures the module can communicate with the backplane.

  • Page 63: Adjustments

    Introduction This chapter contains procedures for adjusting the calibration constants in the Keysight E1418A. Run the Performance Tests (described on Chapter 4) before any adjustments to characterize the module. Run the Performance Tests after any adjustments to verify the adjustments made. The module should be adjusted following any reconfiguration or repair.

  • Page 64: Calibration Constants And Non-Volatile Memory

    If you are adjusting the module more frequently (i.e., daily), write the new calibration constants into RAM, but do not write to non-volatile memory. The adjustment procedures in this chapter demonstrate both methods of writing calibration constants. Keysight E1418A Service Guide...

  • Page 65: Making Connections

    To make the adjustments at each channel output, use the DIAG:CAL:OUTP CHAN command to set the adjustment point at the channels instead of the CAL output terminals. Adjustment at each channel output will require individual four-wire connections. Figure 5-1 CAL Output Terminals Keysight E1418A Service Guide...
