    R&S UPV Troubleshooting CAUTION If there is no measurable voltage or the voltage has an incorrect value and the suspicion exists that the cause is an excessively high output load, it is not advisable just to unplug the connections to the PCB. At certain output voltages the switching power supply needs a certain minimum load in order to operate correctly.

    R&S UPV Troubleshooting Fault in the analog power supply (APS) The effects of a fault: The generator produces either no output signal or a distorted output signal and/or the analyzer either cannot measure or delivers incorrect test results. A first sign of this can occur when booting the R&S UPV, when although the application program starts correctly, the user interface is displayed and there are even no error messages on the screen during the boot procedure, nevertheless no relays can be heard clicking.

  • Page 312: Defective Analog Audio Board (Aab)

    Troubleshooting R&S UPV  Faulty supply voltages for the generator? - Are all cables plugged in at the power input port? If one of the flat-cable connectors on the power input port has no contact, the linear regulators on the APS board cannot produce or stabilize the DC voltages for the generator. - Is the cable from the toroidal core transformer to the APS board (X1) plugged in? The AC supply voltage is fed to the power switch via this connection.

  • Page 313: Defective Analog Signal Generation

    R&S UPV Troubleshooting Defective analog signal generation An initial criterion for correct control of the AAB from the DMB is whether you can hear individual relays while the R&S UPV application program is being started. If not, the DMB may be defective, the control cable may not be connected or the supply voltages from the analog power supply (APS) may be missing.

    Troubleshooting R&S UPV 2. Using an ohmmeter, measure the resistance of the individual voltage pads on the AAB to ground. If the voltages on W13, i.e. those coming directly from the APS, are defective, the APS is one cause of the error (see). However, this may be the result of a short circuit on the AAB. If you do not detect a short circuit when measuring the resistance, material fatigue (ageing) may have caused a blown fuse or some other error on the APS.

    R&S UPV E2PROM Data Management If the E PROM management detects a problem in a subsequent firmware start, it can react positively: If the E PROM is blank but there is a backup on disk, then very probably the E PROM for the module has been swapped and the old content can be restored.

  • Page 389: Recording The Contents

    E2PROM Data Management R&S UPV Recording the Contents Every time the firmware starts, a full scan of all detected E PROMs takes place. The purpose of this scan is to detect modules and their associated hardware options, to read in valid calibration values and to detect special options such as U1 and U2.
