Regulatory Information
Electromagnetic compatibility
The N4000A, N4001A, and N4002A SNS Series Smart Noise Sources comply with
the following Electromagnetic Compatibility (EMC) compliances:
– IEC 61326-1/EN 61326-1
– Canada: ICES/NMB-001
– Australia/New Zealand: AS/NZS CISPR11
In order to preserve the EMC performance of the product, any cable which
becomes worn or damaged must be replaced with the same type and
specification.
Radio-frequency electromagnetic field immunity
When a 3 Vm-1 radio-frequency electromagnetic field is applied to the SNS series
smart noise source according to IEC 61000-4-3, degradation of performance may
be observed. When the frequency of the incident field falls within the bandwidth
of a measured noise figure or gain, the values displayed will deviate from those
expected. This phenomenon will only affect that specific frequency, and the SNS
will continue to perform to specification at all other frequency sample points.
The NFA may be unable to calibrate a chosen frequency sample point, if the
frequency matches that of an incident electromagnetic field.
