• CAT and VNA mode calibrations:
• FieldFox analyzers offer three tiers of calibrations, thus providing users with different levels of calibration:
• effort and accuracy.:
• CalReady:
• CalReady is the most basic calibration and is sufficient for a quick pass/fail or go/no go verification. Every:
• FieldFox is calibrated at the factory, at test ports 1 and 2, at room temperature. CalReady can be applied:
• either as an “enhanced response CalReady” or a “2-port CalReady.” The default setting is 2-port:
• CalReady, so correction is applied to both ports. A user preference allows user to change the CalReady:
• methodology to enhanced response CalReady.:
• A 30-minute warm-up period is recommended for a quick test. A 60-minute warm-up is necessary for:
• more stringent test requirements.:
• If CalReady is the basis for most measurements, the annual cal cycle must be followed, as the CalReady:
• calibration will be updated during the annual cal cycle.:
• Standard calibrations:
• Standard calibrations are the most accurate calibrations offered in FieldFox. FieldFox’s calibration engine:
• is based on Keysight’s flagship PNA calibration engine, and as such, offers many of the standard:
• calibrations. FieldFox supports both coaxial and waveguide calibrations. The table below lists the:
• commonly used calibrations.:
• Keysight recommends a 30-minute warm-up period for standard calibrations. For ultimate in stability and:
• accuracy, a 90-minute warm-up period is necessary.:
• Frequency response:
• Open response:
• Short response:
• Thru response:
• With and without isolation:
• Simultaneous magnitude and phase correction of frequency response errors:
• for either reflection or transmission measurements. Isolation corrects for:
• crosstalk errors.:
• 1-port OSL (Port 1):
• 1-port OSL (Port 2):
• SSL (for waveguide):
• Open, short, and load:
• Traditional 1-port calibration for reflection measurements. Corrects for:
• directivity, source match, and frequency response errors.:
• For waveguide calibrations, depending on the calibration kit definition, this is:
• presented as a short, offset short and load calibration.:
• Enhanced response (also known:
• as one-path, two-port):
• Forward enhanced response:
• Reverse enhanced response:
• Corrects for frequency response and source match. Partial correction for load:
• match for low-loss reciprocal devices.:
• QSOLT (2-port) QSOLT or Quick short-open-load-thru is FieldFox’s default recommended:
• calibration for insertable devices. Full 12-term error correction. Requires fewer:
• connections, compared to traditional SOLT (4 compared to 7). Corrects for:
• directivity, source match, reflection frequency response, load match, and:
• transmission frequency response.:
• Full 2-port (unknown thru:
• calibration):
• FieldFox’s default recommended calibration for non-insertable devices. Full 12-:
• term error correction. Beneficial for characterizing non-insertable devices such:
• as Type-N to 3.5 mm, or female-female devices. Corrects for directivity, source:
• match, reflection frequency response, load match, and transmission frequency:
• response.:
• TRL TRL or thru-reflect-line compensates for directivity, reflection, and transmission:
• frequency response in both the forward and reverse directions.:
• ** Note: FieldFox does not offer the traditional SOLT calibration. Instead, it offers the more accurate Full 2- port (unknown thru),:
• and also QSOLT.:
• ECal:
• FieldFox supports all Keysight USB ECal modules, both standard and value-line ECals.:
• FieldFox’s guided calibration wizard:
• FieldFox’s calibration wizard recommends a calibration type and calibration kit based on selected:
• parameters and connector types. Alternatively, users can select their own calibration type and calibration:
• kit. FieldFox’s calibration wizard ensures a valid calibration selection.:
• Interpolation error correction:
• With any type of accuracy enhancement applied, interpolated mode recalculates the error coefficients:
• when the test frequencies are changed. The number of points can be increased or decreased, and the:
• start/stop frequencies can be changed, but the resulting frequency span must be a subset of the original:
• calibration frequency span.:
• Connectors:
• The FieldFox firmware supports the following connector types by default. Add other connector types with:
• a calibration kit that contains the connector type.:
• Coaxial Waveguide:
• Type-N 50 ohm WR-10 WR-90:
• Type-N 75 ohm WR-15 WR-112:

• Description Model number:
• FieldFox RF & microwave (combination) analyzers N9912C, N9913C, N9914C, N9915C:
• See FieldFox Configuration Guide for option information. Many capabilities listed in this Data Sheet:
• require options.:
• The TDR cable option adds time domain reflectometry (TDR) measurements to FieldFox’s CAT mode.:
• FieldFox’s TDR measurements are based on an inverse Fourier transform of the frequency-domain data.:
• TDR measurements are useful in not only identifying the location of faults along cables, but also the:
• nature of the fault. Resistive, inductive and capacitive faults will each have a different response. These:
• differences help engineers and technicians’ trouble-shoot line faults.:
• Measurements: TDR (linear rho), TDR (ohm), TDR & DTF:
• Y-axis: linear (rho) or impedance (ohm):
• X-axis: distance (meters or feet):
• VNA Time Domain (Option 010):
• In time-domain mode, FieldFox computes the inverse Fourier transform of the frequency-domain data to:
• display reflection or transmission coefficients versus time.:
• Setup parameters:
• Time Start, stop, center, span:
• Gating Start, stop, center, span, and on/off:
• Numbers of points, velocity vector, line loss, window shape, independent control for all four traces:
• Time stimulus modes:
• Low-pass step Low-pass step is similar to a traditional time domain reflectometer (TDR):
• stimulus waveform. It is used to measure low-pass devices. The:
• frequency-domain data should extend from DC (extrapolated value) to a:
• higher value.:
• Low-pass impulse Low-pass impulse response is used to measure low-pass devices.:
• Bandpass impulse The bandpass impulse simulates a pulsed RF signal and is used to:
• measure the time domain response of band-limited devices.:
• Windows:
• The windowing function can be used to filter the frequency domain data and thereby reduce overshoot and ringing in:
• the time domain response.:
• Windows Minimum, medium and maximum, manual entry of Kaiser Beta and:
• impulse width.:
• Gating:
• The gating function can be used to selectively remove reflection or transmission time domain responses. In:
• converting back to the frequency domain, the effects of the responses outside the gate are removed. The results can:
• be viewed with gating on and off, using two traces.:
• Gate types Notch, bandpass:
• Gate shapes Maximum, wide, normal, minimum:
• Mixed-Mode S-Parameters (Option 212):
• Mixed-mode S-parameters are also known as balanced measurements. Not available for N9912C.:
• Measurements:
• Scc11 Common mode reflection:
• Sdd11 Differential mode reflection:
• Scd11 Differential mode stimulus, common mode response:
• Sdc11 Common mode stimulus, differential mode response:
• FieldFox’s mixed-mode S-parameter measurements require the use of the default factory calibration or a:
• user 2-port calibration. So, the FieldFox analyzer must be equipped with 2-port measurement functionality:
• to measure mixed-mode S-parameters. Mixed-mode S-parameters are an extension of the VNA:
• capabilities.:
• Vector Voltmeter (VVM) (Option 308):
• With vector voltmeter mode, you can characterize the difference between two measurements easily. The:
• zeroing function allows you to create a reference signal and characterize the difference between two:
• device measurements. The results are shown on a large display in digital format.:
