Agilent Technologies 4294A Programming Manual page 233

Lines 1200 to 1340 Performs the load compensation in the same way as the open
compensation and creates the multiple channel support compensation
coefficient.
Lines 1380 to 1430 Enters the created compensation coefficient to the 4294A.
Lines 1470 to 1480 Sets the trigger source to the internal trigger and stops the sweep.
Lines 1520 to 1530 In order to use SRQ, enables the instrument event status register's bit 1
(sweep completion) and sets the service request enable register's bit 2
to 1.
Lines 1590 to 1670 Starts the impedance measurement. Displays the message to prompt
the user to connect DUTs to all channels.
Line 1680 Enables the manual sweep function.
Lines 1700 to 1710 Changes the switches of the 3499A to change the channel. A wait time
is provided so that measurement does not start before switching is
complete.
Lines 1720 to 1760 Enables service request interrupts.
Lines 1770 to 1780 Sets the manual sweep range and performs a sweep.
Lines 1920 to 2200 The subprogram to perform the fixture compensation. For more
information, see the description in Example 4-3 on page 65.
Lines 2240 to 2500 The subprogram to set up the 4-terminal pair cable. Its details are as
follows.
Line 2220
Clears the status byte register and the instrument event status register.
Lines 2230 to 2240
Displays the message that prompts the user to make connection for the
measurement specified with Standart$ and waits for pressing the y key
and the return key after the connection.
Lines 2260 to 2270
Sets the branch destination in response to SRQ interrupts and enables
SRQ interrupts.
Lines 2290 to 2340
Sends the command to execute the measurement of the standard
specified with Standard$.
Line 2350
Waits for completion of the measurement.
Lines 2370 to 2380
Displays the message indicating completion of the measurement and
returns 0 as the return value from the subprogram.
Lines 2400 to 2410
The processing when a key other than the y key is pressed. Returns −1
as the return value form the subprogram.
