N4373D Lightwave Component Analyzer, User’s Guide 145
• Number of averages: 1
• 100 Hz IFBW ("Reduce IF bandwidth at low frequency"
enabled) with modulation frequency step size 10 MHz and
measurement points on a 10 MHz raster (if not differently
stated)
• Network analyzer set to "stepped sweep" - sweep moves in
discrete steps"
• Network analyzer configured in reverse coupler
configuration ("RCVB B in" to "CPLR THRU", "SOURCE OUT"
to "CPLR ARM")
• After full two-port electrical calibration using an Electronic
Calibration Module,

N4694A, at constant
temperature (±1°C) with network analyzer set to -15 dBm
electrical output power.
• Modulation-bias optimization set to "every sweep"
• Using the supplied flexible test port cables 1.85 mm f m (Part
number N4697-60200) for NA options x7z and 2.4 mm f m
(Part number 85133-60017) for NA options x4z and x5z.
• Measurement frequency grid equals electrical calibration
grid
• Tested from Port 1 to Port 2, respectively from Port 1 to Port
4 for 4-port PNA
• DUT signal delay
~
0.1/IF-BW
• Specified temperature range: +20°C to +26°C
• After warm-up time of 90 minutes
• Using high quality electrical and optical connectors in perfect
condition
• Using internal laser source
The optical test set always has angled connectors. Depending on
the selected option (-021 straight, -022 angled) the appropriate
jumper cable will be delivered. This jumper cable must always
be used in front to the optical test set to protect the connectors
at the optical test set and is required for performance tests.
