DS335 Setup 2-17 INSTRUMENT SETUP Introduction This section describes the DS335's default settings, storing and recalling settings, setting the computer interfaces, and running self-test. Default Settings Press [SHIFT][+/-] to recall the DS335's default settings. The DS335's default settings are listed below: Setting Frequency Function SYNC ON/OFF Load Impedance Display Amplitude Offset Inversion Sweeps Start Frequency Stop Frequency Trigger Source Sweep/FSK Rate Default Value 1 MHz Sine On 50Ω Frequency 1 Vpp 0.0 V Off Off 1Hz 3.1MHz Continuous 100 Hz Interface RS232 Baud Rate 9600 GPIB Address 22 Storing Setups Recalling Stored Settings GPIB Setup To store the DS335's current setup press [SHIFT][7] followed by a location number in the range 0 - 9. After pressing any UNITS key to enter the location number, the message "sto done" will be displayed, indicating that the settings have been stored. To recall a stored setting press [SHIFT][8] followed by a location number in the range 0 - 9. After pressing any UNITS key to enter the location number the message "rcl done" will be displayed, indicating that the settings have been recalled. If nothing is stored in the selected location, or the settings are corrupted, the message "rcl err" will be displayed. To set the DS335's GPIB interface press [SHIFT][1]. The GPIB enable selection will be displayed. Use the [UP ARROW] and [DOWN ARROW] keys to enable the GPIB interface. Press [SHIFT][1] again to display the GPIB address. Enter the address desired using the numeric keypad or arrow keys. The range of valid addresses is 0 - 30. NOTE: If the DS335 does not have the optional GPIB/RS232 interfaces the message "no GPIB" will be displayed when the GPIB menu is accessed. Only one of the GPIB and RS232 interfaces may be active at a given time, the RS232 interface is automatically disabled when GPIB is enabled. DS335 Synthesized Function Generator
