Using HyperTerminal with Agilent General Purpose Instruments Windows HyperTerminal can be used to program most General Purpose Instruments not the 531xx series counters using the RS 232 Serial Bus Instrument and HyperTerminal Setup Procedure In order to use the instrument with RS 232 the correct cable must be used It is a common mistake that any 9 pin RS 232 cable can be used This is not true Most Agilent instruments use the Null modem cable that is shipped with the instrument If unsure about the cable check the connections using an ohmmeter to the connections shown on page 6 in this document or in the instrument s User s manual 2 Setup the instrument to the factory default RS 232 settings Refer to the instrument User s manual for the settings The settings for some typical instruments are as follows Agilent 34970A Data Acquisition Switch Unit Baud Rate 57600 selectable Data bits 8 selectable Parity None selectable Start bits 1 fixed Stop bits 1 fixed Flow control XON XOFF Agilent 34401A Digital Multimeter Baud Rate 9600 selectable Data bits 8 selectable Parity None selectable Start bits 1 fixed Stop bits 2 fixed Flow control DTR DSR fixed Agilent 33120A Function Generator Arbitrary Waveform Generator Baud Rate 9600 selectable Data bits 8 selectable use this setting to download arbitrary waveforms Parity None selectable use this setting to download arbitrary
