  • Page 795: Special Features Of The Syntax Parsing Algorithms For 8566A And 8568A Models

    <ETX> = Command sections given in [ ] are optional. The R&S FSMR IEC/IEEE-bus hardware differs from that used in the HP analyzers. Therefore, the following constraint exists: <LF>| <EOI> are still used as delimiters since the IEC/IEEE-bus hardware is able to identify them. The other delimiters are identified and evaluated during syntax analysis.
  • Page 796 Bit 2 and 4 are always set in parallel if "Command Complete" or "End of Sweep" are recognized. The R&S FSMR cannot distinguish between these conditions. Additionally these bits are not suitable for synchronization on the end of sweep in continuous sweep operation.

  • Page 797: Model-Dependent Default Settings

    When the IEC/IEEE-bus language is switched over to an 85xx model, the IEC/IEEE-bus address will automatically be switched over to 18 provided that the default address of the R&S FSMR (20) is still set. If a different value is set, this value will be maintained. Upon return to SCPI, this address will remain unchanged.
  • Page 798 Bits 0 and 7 are not used and always have the value 0. It should be noted that the R&S FSMR will report any key pressed on the front panel (if bit 1 was enabled) rather than only the unit keys.

    The following list of commands contains the differences in syntax and behavior between the GPIB command set of the R&S FSMR and the FSE families of instruments. Firmware options like FS-K5 or FSE-K10 are not described in this operating manual as the related commands are not available in the basic instrument.

  • Page 880: Waiting Without Blocking The Keyboard And Mouse

    R&S FSMR Basic Steps of IEC/IEEE-Bus Programming Waiting Without Blocking the Keyboard and Mouse A frequent problem with remote control programs using Visual Basic is to insert waiting times without blocking the keyboard and the mouse. If the program is to respond to user inputs also during a waiting time, control over the program events during this time must be returned to the operating system.

    This can be done by means of the R&S FSMR's LIST PEAKS function, which finds up to 50 peaks in a preselected frequency range and outputs them as a list. The search range can be defined both in terms of frequency and level, and the number of peaks to be found is selectable as well.

    The following example is based on a signal with a level of –30 dBm at 100 MHz. The default setting of the R&S FSMR can also be used for this measurement (SetupInstrument). The objective of frequency counting is to determine the exact frequency of the signal at 100 MHz.

    200 MHz, 300 MHz, etc. In the presence of high-quality signal sources these harmonics may be outside the dynamic range of the R&S FSMR. In order to measure harmonic suppression, however, the level must be set to higher sensitivity for measuring the harmonics; the carrier has to be suppressed by a notch filter to avoid overloading the R&S FSMR RF input.
