N1060A Module Specifications
N1060A module specifications and characteristics apply when a module is installed in the instrument mainframe. The following notes refer to the module specifications listed in this chapter.
- N1000A Regulatory Information and Instrument Markings
- 86100D Regulatory Information and Instrument Markings
An N1060A with a serial number ≥ MY62100101 or ≥ US62100101 requires FlexDCA firmware version A.06.90 or later.
For N1060A modules with a serial number < MY62100101 or < US62100101 The minimum required firmware version is A.06.00 (FlexDCA) for both the 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.

PLL bandwidth is calibrated and verified using a clean NRZ, PRBS13 signal.
Actual PLL bandwidth may vary due to several factors, including pattern characteristics
(low/high transition density), signaling format (PAM4), and signal quality (closed eyes).
