Using the VFP Data Upload Library

VFP Data Upload Library

VFP Data Upload Library is an subprogram library used for loading data (that was

made and saved by the Virtual Front Panel utility) to your program. The library

contains the following four subprograms. The library runs on HP BASIC.

Loads data file (that was created and saved by Virtual Front Panel utility) to your

program. The file contains all data from the 24 Setup Memories, and setup mode

data for initializing the E5250A.

Syntax: Load_vfp_data(Address_5250,"LOAD_FILE",Setup_data$)

Parameters: Address_5250: GPIB address of the E5250A.

LOAD_FILE: File name of data you want to load.

Setup_data$: Data string for internal use in the library. Must declare 14000

byte data size.

Example: CALL Load_vfp_data(722,"MAT48_1",Mat48_data$)

Initializes the E5250A based on the setup mode data loaded by the Load_vfp_data

subprogram. This subprogram sets the following parameters:

• Configuration Mode: Auto or Normal

• Connection Rule: Free

• Connection Sequence: Break Before Make

• Bias State: Bias Mode (ON/OFF) for each card.

• Input Bias Port for each card.

This subprogram must be entered before the Connect_vfp subprogram.

Syntax: Init_vfp_setup(Setup_data$)

Parameter: Setup_data$: Data string for internal use in the library. Must declare 14000
