Using the TTY setup menu

You can view and modify most RVP10 operating parameters with the TTY setup menu. For example:

  • Make TTY connections

  • Save and restore configurations

    For example, you can configure custom trigger patterns, pulse width control, matched FIR filter specs, PRF, and so on, in the field.

  • Access graphical setup and monitoring procedures that use an ordinary oscilloscope as a synthesized visual display.

    The burst pulse and receiver waveforms are displayed in the time and frequency domain.

    The digital FIR filter matches the characteristics of the transmitted pulse.

  1. To access the TTY menu:
    1. In the serial TTY or host computer interface, type: dspx

      The following prompt is shown:

      $dspx
Digital Signal Processor 'Chat' 
Checking for code upgrades...Okay 
(Type ^C to exit Chat Mode)
    2. On the TTY, press ESC.

      RVP10 command prompt is shown (example):

      Vaisala, Oyj
RVP10 Digital IF Signal Processor V15 IRIS-10.0.0-rc1
--------------------------------------------------- 
Intermediate Frequency Digital Receiver.
IFDR firmware version 1.0.0
-----------------------------------------
RVP10>
  2. To view RVP and IRIS software versions, type V
  3. For a list of available commands, type help
  4. To exit the menu and reload RVP10 with the changed set of current values, type: Q

    Settings are saved in a configuration file so they take immediate effect on start-up.

    You must exit the menus using the Q before resuming normal RVP operation.

    Portions of the RVP command interpreter continue to run while the menus are active, but the processor does not function until you exit the menus.

  5. To return to the Linux command prompt, press SHIFT > C.
