Option Descriptions
Option 010, Vector Network Analyzer Time Domain
With Option 010 or time domain, FieldFox computes the inverse Fourier
transform of the frequency-domain data to display reflection or transmission
coefficients versus time. Time domain gating can be used to remove unwanted
responses such as connector mismatch or cable discontinuities, and the
results can be displayed in either time or frequency domain.
— Fully error-corrected time domain reflection or transmission response
— Gating available to remove unwanted responses
— View time and frequency domain data simultaneously
— Transform frequency domain to the time domain or time domain to the
frequency domain
Option 030, Remote Control Capability
Option 030 adds remote control capability to FieldFox for iDevices.
— User must supply iPad, iPhone, or iPod.
— User must download free FieldFox app from App store.
Option 100, 3.5 mm APC Connectors
Option 100 provides 3.5 mm input and output connectors.
Available on N9938A model only (26.5 GHz) at initial purchase.
Option 112, QuickCal
Option 112 provides a calibration that is performed automatically using
calibration standards that are built-in to the FieldFox. Calibration standards are
automatically switched in as needed. QuickCal is ideal for making quick DTF
and cable loss measurements without taking the time to perform a full O,S,L
Cal.
Option 208, USB Power Sensor Measurements versus Frequency
Option 208 enables a power measurement versus frequency. The power is
measured using a USB power sensor. FieldFox's source frequency can be set
independently from the power sensor (receiver) frequency. The frequency of
both the source and receiver are swept, and the two track each other. The
offset frequency can be negative, zero, or positive.
