N1077A DCA-M Specifications
N1077A DCA-M specifications and characteristics apply when the temperature is within the range noted below. Use the DCA-M's rear panel USB Type B connector to connect the DCA-M to a DCA-X mainframe or to N1010A FlexDCA on a PC. The DCA-M is connected as a USB 2.0 device. For additional information concerning the required firmware versions refer to DCA-M compatibility with N1000A and 86100D.
All specifications describe warranted performance over the temperature range +10° C to + 40° C (unless otherwise noted). The specifications are applicable after the temperature is stabilized, which occurs after 1 hour of continuous operation and while module calibration is valid. Many performance parameters are enhanced through frequent, simple user calibrations.
Specifications describe warranted performance. Characteristics provide useful, nonwarranted information about the functions and performance of the instrument. Characteristics are printed in green italics.
Factory Calibration Cycle. For optimum performance, the instrument should have a complete verification of specifications once every 12 months.
Nominal Value indicates the expected, but not warranted, value of the parameter.
