Digital Step Attenuator ZX76-31-PN ZX76-31-PN+ Mini-Circuits Recommended Accessories Two optional cable accessories with and without interface connector are available with ZX76-31-PN(+), the ZX76-CP+ and ZX76-WP+. Cable length is 4.9 feet / 1.5 meters. ZX76-CP+ shielded cable with interface 25 pin D-type connector J4 and supplied software are used to control the ZX76-31-PN(+) digital attenuator from a computer, using LPT port. ZX76-WP+ shielded cable without interface 25 pin D-type connector enables customer to use the ZX76-31-PN(+) digital attenuator in his own application. Note: Mini-Circuits can supply control cables with other options for the J4 connector and/or different cable lengths. Consult factory with your specific requirements.
