8719ES/20ES/22ES Analyzer Options
RF Network Analyzers
Analyzer Options
Option 1D5, High Stability Frequency Reference
Option 1D5 offers ±0.05 ppm temperature stability from 0 to 55 °C (referenced to 25 °C).
Option 004, Step Attenuator (ET Models)
This option adds a 55 dB step attenuator into the RF output path.
Option 007, Mechanical Transfer Switch (ES Models)
This option replaces the solid state transfer switch with a mechanical transfer switch,
providing the analyzer with greater power handling capability. Because the mechanical
transfer switch has less loss than the solid state transfer switch, the output power of an
Option 007 analyzer is 5 dB higher.
Option 010, Time Domain
This option allows the analyzer to display the time domain response of a network by
computing the inverse Fourier transform of the frequency domain response. The analyzer
shows the response of a test device as a function of time or distance. Displaying the
reflection coefficient of a network versus time determines the magnitude and location of
each discontinuity. Displaying the transmission coefficient of a network versus time
determines the characteristics of individual transmission paths. Time domain operation
retains all accuracy inherent with the active error correction.
Option 012, Direct Access Receiver Configuration (ES Models)
This option provides front panel access to the A and B samplers. This allows direct access
to the sampler inputs for improved sensitivity in applications such as antenna tests, or for
the insertion of attenuators between the couplers and samplers. Direct access to the
B (A) sampler provides increased dynamic range in the forward (reverse) direction.
