N1090A Specifications
N1090A DCA-M optical/electrical sampling oscilloscope 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.
The N1090A must be controlled from a PC, N1000A, or 86100D that is running FlexDCA firmware version ≥A.06.00 or higher for an N1000A or FlexDCA firmware version between A.05.00 and A.07.60 for an 86100D. 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.
Nominal Value indicates the expected, but not warranted, value of the parameter.
Factory Calibration Cycle. For optimum performance, the N1090A should have a complete verification of specifications once every 12 months.
The Mains wiring and connectors shall be compatible with the connector used in the premise electrical system. Failure, to ensure adequate earth grounding by not using the correct components may cause product damage, and serious injury.
