VXI or LAN In addition to sending commands and queries the host can upload waveform data for arbitrary waveform generation Each output channel has dual DAC memory buffers of up to 32 MiSamples 64 MiB in depth While one buffer feeds a data stream to its DAC for conversion to the analog output the other buffer can be loaded with the next waveform to be generated This dual ping pong buffer architecture enables instantaneous seamless waveform switching upon command trigger event or modulation input state Each DAC memory buffer can be loaded with standard functions generated by the DSP arbitrary waveforms uploaded from the host or waveform sequences that piece together arbitrary waveforms in stages to create compound waves When generating waveform sequences the DSP uses the arbitrary waveform library or the four reference waveforms The arbitrary waveform library provides up to 8 MiSamples 16 MiB in total memory that can be loaded with up to 4096 arbitrary waveforms The four reference waveforms REF1 4 are each up to 32 KiSamples 64 KiB in length and use non volatile memory that is maintained when the unit is powered off 0004 000074 23 Clock Generation and Synchronization DAC Sampling Clock The instrument supports flexible digital to analog converter DAC sampling clock configurations All internal sampling clocks are synchronized by a phase locked loop PLL that is locked to the 10 MHz time base reference Each individual

15. Event registers range in length from 1 to 16 bits and may contain unused bits Unused bits will return a zero 0 when the register is read An event becomes TRUE when the associated device condition transitions to a TRUE state The event register guarantees that the application cannot miss a condition that is removed before the condition register can be read An event register bit will be set TRUE when an associated event occurs These bits once set cannot be cleared even if they do not reflect the current status of a related condition until the event register is read by the application Also the instrument provides a command to clear all event registers Note Event bits are cleared when read Enable An enable register selects which event bits in the corresponding event register will cause a TRUE summary output when an event occurs The summary output enabled by the event enable register is used to propagate the status summary to the next status level Each event bit in the event register has a corresponding enable bit in the event enable register When an event enable bit is TRUE the corresponding event will propagate to the status summary output Any unused bits in the event enable register correspond with unused bits in the event register The value of unused bits is zero 0 when the event enable register is read and is ignored when written to by commands 0004 000074 53 Self Test The instrument can initiate an instrument self
