67 GHz Single-Mode Lightwave Component Analyzer for 40/100G electro-optical test

HP => Agilent Technologies 

Specifications for electrical-electrical measurements (E/E mode)

All specifications of the E8361C-014 Network Analyzer apply.

Please see the corresponding Network Analyzer data sheet and User’s Guide.

Group delay uncertainty

For more details see specifications of the E8361C.

Group delay

Group delay is computed by measuring the phase change within a specified

aperture (for aperture see below:

Phase change [deg]

GD [s] = -----------------------------------------

(1)

Aperture [Hz] * 360

Group delay uncertainty

Is calculated from the specified phase uncertainty and from the aperture (for aperture see below):

Phase uncertainty [±deg]

GD [±s] = --------------------------------------- *sqrt(2)

(2)

Aperture [Hz] * 360

Aperture

Determined by the frequency span and the number of points per sweep:

Aperture:

(frequency span) / (number of points–1)

GD Range

The maximum group delay is limited to measuring no more than ±180 degrees of

phase change within the selected aperture (see Equation 1).
