N1000A Specifications
This section lists the specifications for the N1000A mainframe.
An N1000A with a serial number ≥ MY62100101 requires FlexDCA firmware version A.06.90 or later.
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 self calibration is valid.
The N1000A time base has humidity-sensitive components. The amount of moisture accumulated in the instrument depends on the length of time it has been powered off as well as ambient humidity. Under certain measurement conditions and environments, the jitter may be temporarily higher than the specified limit after a unit has been recently turned on. If the jitter exceeds the specification it is recommended to allow the instrument to stay powered on for 24 hours to allow the humidity within the system to stabilize. 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 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.

N1000A internal precision timebase specifications (Option PTB)
The N1000A Internal Precision Timebase Specifications are for Option PTB, which is the N1000A internal precision timebase. These specifications refer to the signal input to the front-panel Precision Timebase Input connector.
If Freerun trigger mode is not used, a trigger input must also be supplied. This is in addition to the reference clock input to the front-panel Precision Timebase connector. The trigger input must be synchronous to the reference clock but may be a sub-rate of the clock based on the required frequency range for the trigger input.
| Item | Description |
|---|---|
| Maximum Input Signal | 1.3 Vpp |
| Input DC Offset Range | ± 200 mV |
| Input Signal Type The internal precision timebase works with typical digital clock signals, such as a BERT output, as well as sine waves. If the rise time or fall time of the clock signal is less than 15% of the period of the clock (for example, less than 15 ps for a 10 GHz clock), reduce the edge speed by using an external low-pass filter or length of cable. For the lowest jitter, use a signal that is as close as possible to the maximum signal amplitude (1.3 Vpp) and minimize any sub-harmonics. |
