  • Page 41: Troubleshooting Introduction

    7. Perform the 7. Inspect the Rear Panel Feature in this chapter. If the E4915A/E4916A has passed all of the checks in steps 2 through 7 but it still making incorrect measurements or unexpected operations, suspect the accessories. Accessories such as PI Test Fixture or Impedance Probe, calibration devices, can all induce system problems.

  • Page 42: Inspect The Power On Sequence

    Turn the E4915A/E4916A power on. Inspect the fan on the left side. The fan should be rotating and audible. In case of unexpected results, check AC line power to the E4915A/E4916A. Check the fuse (rating listed on the rear panel). If the problem persists, continue with the 3. Troubleshoot the Power Supply section.
