With an integrated pattern generator, the Keysight 1663EP has the same function as the Keysight 1663E product but with the capability to let designers functionally test their digital design with a 32-channel, 100 M vector/sec, 256 K vector deep stimulus program. You could stimulate the device under test and then see how it is responding to certain clock speeds or signals. You can also use the pattern generator to substitute for missing sub-systems. Speeds of stimulus of 200 M vectors/sec are probable on up to 16 channels. Wait commands, initialization sequences, and program macros let complex stimulus programs be generated. The all-in-one, compact design saves space on a crowded lab bench.
