	Keithley Model 776 Counter/Timer TestPoint Library
	--------------------------------------------------

	Users Notes:

	The 776 TestPoint Library is User Defined Object that provides
	the user with pre-defined actions that can be used to program
	the 776 for a variety of functions.

	The default IEEE-488 address of the 776 is set at the factory 
	for 14. The 776 Library is set for the default address of 14.
	Should you wish to change the 776 library address to something
	other than 14, double-click on the 776 icon. You can change the
	address to the specific address you wish to use.

	The actions for pre-defined for the 776 Library are as follows:


	Reset 776
	Trigger 776
	Read Value
	Set Function
	Set Channel A Parameters ----->  Set Channel A Coupling
			Set Channel A Trigger Level 
					 Set Channel A Attenuation
					 Set Channel A Filtering
					 Set Channel A Slope
					 Set Channel A Impedance
	Set Channel B Parameters ----->  Set Channel B Coupling
			Set Channel B Trigger Level 
					 Set Channel B Attenuation
					 Set Channel B Filtering
					 Set Channel B Slope
					 Set Channel B Impedance
	Set Totalize Mode
	Set Delay Time
	Set Gate Time
	Set Operational Functions
	Set Trigger
	Set Display Mode
	Set Data Control
	Set Terminator

	When creating your application, the 776 Icon is dragged from the
	Object List into the Action List. When this process is performed,
	the above list of selections is provided. The user can then select
	the action he or she wish to perform on the 776. The actions are
	described below:


	'Reset'
	 -----
	Reset sends a Device Clear to the 776.


	'Trigger 776'
	 -----------
	The GPIB Trigger action sends a Group Execute Trigger (GET) to the
	776 for triggering the 776 when using bus triggering.


	'Read Value'
	 ----------
	Read Value performs the action of reading a value from the 776.


	'Setup Function'
	 --------------
	This action allows the user to set the measurement function of the
	776. These include Frequency, Period, Pulse, Time Interval, Ratio,
	Phase, Period Average, and Pulse Average.

	
	'Set Channel A Parameters ----->  Set Channel A Coupling'
	 -------------------------------------------------------
	This action allows the user to set channel A coupling to DC Coupling
	or AC Coupling.


	'Set Channel A Parameters ----->  Set Channel A Attenuation'
	 ----------------------------------------------------------
	This action allows the user to set channel A Attenuation to X1 or 
	X10.


	'Set Channel A Parameters ----->  Set Channel A Filtering'
	 --------------------------------------------------------
	This action allows the user to set channel A filtering Off or On.


	'Set Channel A Parameters ----->  Set Channel A Slope'
	 ----------------------------------------------------
	This action allows the user to set channel A Slope to Positive
	or Negative.


	'Set Channel A Parameters ----->  Set Channel A Impedance'
	 --------------------------------------------------------
	This action allows the user to set channel A Impedance to 1Mohm
	or 50 Ohm.


	'Set Channel A Parameters ----->  Set Channel A Trigger Level'
	 ------------------------------------------------------------
	This action allows the user to set channel A Trigger Level from
	-50 to 50.


	'Set Channel B Parameters ----->  Set Channel B Coupling'
	 -------------------------------------------------------
	This action allows the user to set channel B coupling to DC Coupling
	or AC Coupling.


	'Set Channel B Parameters ----->  Set Channel B Attenuation'
	 ----------------------------------------------------------
	This action allows the user to set channel B Attenuation to X1 or 
	X10.


	'Set Channel B Parameters ----->  Set Channel B Filtering'
	 --------------------------------------------------------
	This action allows the user to set channel B filtering Off or On.


	'Set Channel B Parameters ----->  Set Channel B Slope'
	 ----------------------------------------------------
	This action allows the user to set channel B Slope to Positive
	or Negative.


	'Set Channel B Parameters ----->  Set Channel B Impedance'
	 --------------------------------------------------------
	This action allows the user to set channel B Impedance to 1Mohm
	or 50 Ohm.


	'Set Channel B Parameters ----->  Set Channel B Trigger Level'
	 ------------------------------------------------------------
	This action allows the user to set channel B Trigger Level from
	-50 to 50.


	'Set Totalize Modes'
	 ------------------
	This actions allows the user to specify the Totalizing modes, 
	specifically, Totalize infinitely on B, Totalize on B gate by A, or
	Totalize on B gated by AA.

	
	'Set Delay Time'
	 --------------
	This action allows the user to set a measurement delay time from 0
	to 9.9E9 seconds


	'Set Gate Time'
	 -------------
	This action allows the user to set a specific gating time from 0 to
	9.9E9 seconds
	
	.
	'Setup Operational Functions'
	 ---------------------------
	This action allow the user to setup various 776 operational features
	such as Auto Trigger Level, Vpeak, Measurement Rate, Totalizing 
	Modes, Ratio Mode, and the number of Displayed Digits.


	'Setup Trigger'
	 -------------
	This action allows the user to set the triggering of the 776.


	'Setup Display Mode'
	 ------------------
	This action allows the user to set the 776 for a particular
	display mode.

	
	'Setup Data Control'
	 ------------------
	This action allows the user to setup various data control strings
	and the Prefix control strings.


	'Setup Terminators'
	 -----------------
	This action allows the user to choose a terminator string for the
	776.

	=================================================================
	Notes:
	GPIB Address: Should the user wish to alter the address of the 
	776 icon, you can double click on the icon in the object window. 
	A settings panel will appear that will allow the user to change 
	the GPIB address for TestPoint. This does not physically change 
	the address on the 776. Additionally, the user can put the library 
	into DEMO MODE by clicking the appropriate box in the settings panel.



	The library covers a large percentage of the 776 operation but
	not 100% of all of the functions. Any function of the 776 can be
	programmed using a GPIB object in your application and programmed
	directly. For further assistance on programming the 776, you can
	contact the Keithley Instruments Application Engineering group at
	800-348-3735 Monday through Friday between 8:00AM and 5:00PM EST.
