The Serial Data Transfer option allows the user to transfer serial digital data to the Modulation Inputs for Frequency and Phase shift keying schemes as well as the Shape Keying input.  The transfer size is from one byte to 512K bytes per channel added.  The data may be looped from start to finish for bit rate testing from a single file or multiple files in a control sequence from applications like LabView or any application that will allow the execution of an executable (*.exe) file.  This option is similar to the PMG-130 transfer option and is a separate module that attaches to the PMG-M-130 main PCI board. Up to six separate channels may be attached to the PMG-M-130 to accommodate three SHAPE and three FREQUENCY/PHASE modulation input pins selectable from the MOD-In Dialog.  The module also includes a scan control data transfer unit.  The scan control unit allows the user to setup an automatic scan test of an unlimited number of test frequencies and digital outputs.  Each Frame of the scan Block is controlled by a user created recipe file.  The serial output of the Data Transfer modules feed the modulation matrix inputs as shown in the Modulation Matrix Selection.

OPTIONAL DIGITAL SERIAL DATA TRANSFER CONTROL MAIN WINDOW

 CHANNEL 1  FREQ/PHASE and SHAPE SECTION  - This is the main section for channel 1. The user has the option of manually changing state (<-PROGRAM CONTROL->) or serial data transfer mode shown below.

 CHANNEL 2  FREQ/PHASE and SHAPE SECTION  - This is the main section for channel 2. The user has the option of manually changing state (<-PROGRAM CONTROL->) or serial data transfer mode shown below.

 SETUP SERIAL DATA TRANSFER  - When not in PROGRAM CONTROL mode the user may enter the Data Transfer Dialog for data file transfer.

 CHANNEL 3  FREQ/PHASE and SHAPE SECTION  - This is the main section for channel 2. The user has the option of manually changing state (<-PROGRAM CONTROL->) or serial data transfer mode shown below.

 STATUS OF LAST COMMAND - This is a monitor field for the status of the last command executed in the dialog.

 Mark(1) Space(0) - This section allows the user to select the state of the SHAPE input line.

 Change SHAPE Data  - This button allows the user to manually change the state of the SHAPE line selected in

  Mark(1) Space(0) - This section allows the user to select the state of the MOD-IN  input line.

Change MOD Data  - This button allows the user to manually change the state of the SHAPE line selected in

 RETURN TO MAIN MENU


 

OPTIONAL DIGITAL SERIAL DATA TRANSFER CONTROL WINDOW

 DATA TRANSFER MAIN MENU - The main menu for this dialog allows the user to Load and Save data files or create a new file.  All data loaded or created is placed in the working array buffer until the user transfers it to the on board SRAM by the Write to SRAM button.

 CURRENT FILE  - This is the current data file loaded in to the working array buffer displayed with its full path.

 STORE DATA to ARRAY  - The Store DATA to ARRAY Button allows the user to edit current data or create new data in the working array.

 WORD COUNT SETUP  - The word count allows the user to select a desired word count from the array. This function works with the SRAM starting address in order to allow a windowed data transfer from the array. This allows the user to store several frames in SRAM and select the frames desired for the test.

 TRANSFER MODE SETUP - The transfer mode setup allow the user to select a SINGLE WORD, SINGLE BLOCK, or FULL BLOCK transfer. The word size is also variable from 1 to 16 bits.  The user may also select the start and end bit in the word allow word windowing as well. The transfer mode also allows the user to control the bps rate of the transfer by controlling the reference frequency and rate divider.

 STATUS OF LAST COMMAND - This is a monitor field for the status of the last command executed in the dialog.

 TRANSFER DATA  - This is where the data is transferred to the active core of the PMG-M-130.  The SINGLE and BLOCK transfer buttons allow the user to control a single word transfer or and entire block (word count) transfer.

 HELP - This Button will activate the About dialog box and allow the user to select the online manual for help.

LOAD MODE & SERIAL DATA REGISTER  - These buttons insure a relative starting point for the data transfer.

 DATA LOOP CONTROL  - This section is for diagnostics. It allows the data in the array to be looped indefinitely or to a specific loop count.

 SRAM START ADDRESS  - This is the starting address in the SRAM of the data to be transferred to the active core.

 DATA IN CURRENT ARRAY - This is the current working array data window that will allow the user to verify and edit the data prior to transfer.


MODULATION INPUT SOURCE SELECT

The Modulation Input Select dialog also the user to control the serial data output from the Serial Data Transfer units and/or allow the user to use one of the input selections as a USER Input with a user supplied bit stream. The Dialog below shows that the user may also select program control of the modulation and shape inputs. program control. This allows the user to use the IBR under Scan control to control the state of the modulation and shape inputs. The three inputs are accessible via an internal header connector on board.
