DTF (Distance to Fault) Measurements DTF Measurement Settings Typically, you will set the frequency range of the measurement to the passband of the filter. However, you may also want to test the ability of the filter to reject unwanted frequencies. In this case, set the frequency range to include those frequencies which the filter may not be adequately rejecting.
Page 69 DTF (Distance to Fault) Measurements DTF Measurement Settings About Velocity Factor and Cable Loss — Velocity Factor is a property of the physical material of a cable. A VF of 1.0 corresponds to the speed of light in a vacuum, or the fastest VF possible. A polyethylene dielectric cable has VF = 0.66 and a cable with PTFE dielectric has VF = 0.7.

Why and When to Calibrate There are well-defined and understood systematic errors that are measured and calculated during the calibration process. These errors are caused by leakage signals inside the FieldFox, by the frequency response of the FieldFox receivers, and by reflections inside the FieldFox that interact with the DUT.

Calibration for NA, CAT, and VVM ModesFUTURE scope of this discussion. Although an OPEN standard is a precision component, simply leaving nothing connected at the end of a cable can be a reasonable substitute for an OPEN. — A LOAD standard absorbs almost ALL of the incident signal and very little signal is reflected back to the source.

Page 720 Noise Figure Mode (Option 356) Calibration Wizard Calibration Wizard The Noise Figure mode has two types of calibration wizard softkeys: Receiver Cal and User Cal. A receiver calibration is required for a user calibration.

The receiver calibration has virtually no influence on the noise figure measurement, either with or without a user calibration.

Page 723 Noise Figure Mode (Option 356) Calibration Wizard User Calibration (User Cal): Performing a user calibration is recommended only when the measurement setup includes a preamplifier. The user calibration is unnecessary for accurate measurements when no preamplifier is used. In general, a user calibration should be performed whenever a preamplifier is used in the noise figure measurement.

Page 725 Noise Figure Mode (Option 356) Calibration Wizard Optimizing Measurement Accuracy: — Both gain and noise figure measurement accuracy will be enhanced by using a noise source with as low a reflection coefficient as possible for the user calibration. — When the DUT output noise power is relatively low (i.e., the gain plus noise figure of the DUT is less than 15 dB), measurement accuracy may also be improved by using a low loss isolator on the preamplifier input.

The FieldFox is also designed for use in Installation Category II and pollution Degree 2 per IEC 61010-1.
Page 850 Safety Considerations For the FieldFox For the FieldFox No operator serviceable parts inside except for the lithium-ion battery. Refer servicing to qualified personnel. To prevent electrical shock do not remove covers. If this product is not used as specified, the protection provided by the equipment could be impaired.
Page 851 Safety Considerations For the FieldFox When performing a measurement, ensure that the right safety and performance ratings of the instrument and accessories are used. Do not expose the circuit or operate the instrument without its cover or while power is being supplied. Do not operate the instrument in any environment at risk of explosion.
Page 852 Safety Considerations For the AC/DC Adapter For the AC/DC Adapter Use only the designated AC/DC adapter supplied with the instrument. Use only the designated power cord supplied with the AC/DC adapter. Operated at an ambient temperature: 0 to 40°C; full power rating; derate linearly at a rate of 3 watts per degree C, from 90W at 40°C to 45W at 55°C, 30W at –20°C.

Be sure to follow these safety warnings: External battery, U.S.
Page 855 Safety Considerations For the Battery Do not solder directly onto the battery. Do not expose the battery to water or salt water, or allow the battery to get wet. Do not disassemble or modify the battery. The battery contains safety and protection devices, which if damaged, may cause the battery to generate heat, explode, or ignite.
Page 856 Safety Considerations For the Battery Standard Capacity Battery (N9910X-870) Lithium–ion batteries: — Must not be exposed to high temperatures (>70°C) or fire. — Must be kept away from children. — Must not be short circuited. — Must be replaced only with Keysight qualified Li–ion batteries. —...
Page 857 Safety Considerations For the Battery Do not discharge the battery using any device except the FieldFox or the external battery charger (N9910X–872). When the battery is used in a device other than those specified, it may damage the battery or reduce its life expectancy. If the device causes an abnormal current to flow, it may cause the battery to become hot, explode, or ignite and cause serious injury.
Page 858 Safety Considerations Battery Protective Functions Battery Protective Functions This section contains the following: — “Battery Protective Functions (N9910X-876)” — “Battery Protective Functions (N9910X-870)” on page 854 Battery Protective Functions (N9910X-876) The following protective functions are designed into the lithium-ion rechargeable battery system used in FieldFox. The protective functions can be divided between two categories: active and passive.
Page 859 Safety Considerations Battery Protective Functions Overtemperature Discharging: The system microcontroller prevents the battery from being discharged if the cell temperature exceeds 67C. Once the overtemperature discharging protection is tripped, the battery is automatically shut off which results in turning off the instrument as well. Passive Protection Reverse Charging: A reverse protection diode prevents against damage or lost data due to a reverse charge polarity applied to the battery terminals.
Page 860 Safety Considerations Battery Protective Functions Battery Protective Functions (N9910X-870) The following protective functions are designed into the lithium-ion rechargeable battery system used in FieldFox. The protective functions can be divided between two categories: active and passive. Active protection refers to the type of protection that depends on at least two or more protection devices working together to enable the protection Passive protection refers to the type of protection that is always enabled independent of any other protection device.
Page 861 Safety Considerations Batteries: Safe Handling and Disposal Overtemperature Charging: The system microcontroller prevents the battery from being charged if the cell temperature exceeds 46C. Once the overtemperature charging protection is tripped, the cell temperature has to drop to or below 45C to reset the protection and permit charging. Overtemperature Discharging: The system microcontroller prevents the battery from being discharged if the cell temperature exceeds 65C.
