Changing the HP-IB Address
CHANGING THE HP 3326A HP-16 ADDRESS
The HP 3326A address can be set at any address between 0 and 30, inclusive. The
HP-IB address of the HP 3326A is set to 18 at the factory and stored in nonvolatile
memory. When selecting an address, remember that the controller also has an address
(usually 21).
To change the HP-IB address:
Press the blue SHIFT key followed by the LOCAL key in the HP-IB
STATUS block to display the HP-IB address.
Enter the address with the numeric keypad. For two digit HP-IB ad-
dresses, the address is set when the second digit is entered. For
single digit HP-IB addresses, the address is set when any units key
is pressed. Alternately, a zero can precede the single digit to form
a two digit address.
NOTE
The HP-IB address is reset to 18 after a memory
clear opera tion.
The message "Error 20 RNGE" is displayed if the HP-IB address ex-
ceeds 30.
INTERROGATING THE H P 3326A FOR SETUP PARAMETERS
The value of a setup parameter is read over the HP-IB by sending the parameter HP-IB
mnemonic followed by a question mark (?). The HP-IB command summary table lists
the parameters that can be interrogated and the form of the response. For example,
sending the mnemonic FR? sets up the HP 3326A to respond with the frequency value
for the selected channel. The frequency value is transmitted when the HP 3326A is
addressed to talk. Each value is returned with units.
The HP 3326A always responds with the units Hertz for frequency values, volts peak-
to-peak for amplitude values, seconds for time values, volts dc for offset values, degrees
for phase, and percent for duty cycle. The HP 3326A responds with either percent or
degrees for modulat~on level. Each interrogation response ends with a carriage return
(ASCII 13) and line feed (ASCII 10) character.
DISPLAYING THE HP 3326A SETUP PARAMETERS
The current value for a setup parameter is displayed on the HP 3326A front panel if
the corresponding HP-IB mnemonic is sent without data and a suffix. For example, send-
ing the mnemonic AM displays the amplitude value for the selected channel but does
not change the amplitude value.
