| Note 1 每 All residual THD+N specifications are with a 2Vrms 1KHz sine wave and 80KHz bandwidth limiting (ATS-2 is limited to 30KHz). |
|
Note 2 每 Probably not needed because of bandwidth limiting of the A/D. |
| Note 3 每 AES17 is not functional with
GPIB. |
| Note 5 每 Random, square wave, & eq sine jitter is not available. Rise & fall time adjustment is not available. Cable simulation is not available. |
| Note 6 每 Random & square wave jitter is not available. Rise & fall time adjustment is not available. Cable simulation is not available. |
| Note 7 每 PCI APIB interface card is not compatible with WIN95. |
| Note 9 每 National Instruments IVI driver is only available with the SYS-2022G, SYS-2222G, SYS-2300G, & SYS-2322G. |
| Note 10 每 GPIB is not yet available for the SYS-2722 with 192k DIO. SYS-2722G Cascade Plus with 96k DIO is still available. |
| Note 11 每 SYS-2702 is identical to SYS-2122 and SYS-2712 is identical to SYS-2622. |
|
| All specification subject to change without prior notice for product modification or improvement. |
