Agilent Technologies Model 6684A: 3339A-00101 Manual Do Utilizador

 Whenever you wish, you can return the power supply to the original factory reset state. To do this, simply hold down the 
key when you turn on the supply. The display indicates RST POWER-ON to verify that the power supply has configured
its turn-on state to the original reset state. From now on it will continue to turn on in that state.
 
 

 
 Figure 4-6 in Chapter 4 shows the ways the power supply can be connected to the GPIB bus. You can set up the GPIB
address in one of three ways:
 
  1. As a stand-alone supply (the only supply at the address). It has a primary address in the range of 0 to 30. For example:

5 or 7.

 
  2. As the direct supply in a serial link. It is the only supply connected directly to the GPIB bus. The primary address is

unique and can be from 0 to 30. It is entered as an integer followed by a decimal separator. The secondary address always
is 0, which may be added after the primary address. If the secondary address is omitted, it is assumed to be 0. For
example: 5.0 or 7.

 
  3. As a linked supply in serial link. It gets its primary address from the direct supply. It has a unique secondary address

that can be from l to 15. It is entered as an integer preceded by a decimal separator. For example: .l or .12

 
 When you enter a secondary address, leading zeros between the decimal separator and the first digit are ignored. For
example, .1, .01, and .001 are accepted as secondary address 1 and displayed as  0.01. Zeros following a digit are not
ignored. Thus, .10 and .010 are both accepted as secondary address 10 and displayed as  0. 10.

 
 Use  the 

 key and numerical keypad for entering addresses. The power supply is shipped with a 5 stand-alone

address as the default. The general procedure for setting an address is:
 

 Action

 Display Shows

 Press 

 Current  address

 Press new address keys

 New address replaces numbers on the display

 Press 

 Display returns to meter mode

 
 If you try to enter a forbidden number, ADDR ERROR is displayed.
 
 The following examples show how to set addresses:
 

 To set stand-along primary address 6, press 

.

 To set direct supply primary address 6, press 

.

 To set linked secondary address 1, press 

.

 To set linked secondary address 12, press 

.

 

The power supply display will reset (recall the state in location 0) whenever you change between the
 following types of GPIB addresses:

 

•

  a stand-alone primary address and a direct primary address.

 

•

  a direct primary address and a secondary address.
