Option 305, Cable and Antenna Analyzer
Option 305 provides fast and accurate diagnosis of cables, connectors, and
antennas with DTF (dB, linear, VSWR), return loss and DTF, 1-port cable loss,
2-port insertion loss, and CalReady.
Option 307, GPS Receiver
Option 307 enables the built-in GPS receiver. Requires a GPS antenna such as
N9910X-825.
Option 308, Vector Voltmeter (VVM)
Option 308 includes S11 or one-port cable trimming.
Option 309, DC Bias Variable-Voltage Source
Option 309 adds an integrated built-in variable voltage DC bias source to the
FieldFox analyzer. The source provides 1 to 32 VDC with maximum current of
650 mA and 7 watts maximum power. The DC bias source can provide DC
power to amplifiers under test and bias tower mounted amplifiers (TMA) when
engineers need to sweep through the TMA to reach the antenna. The bias-tee
is available separately. The DC output has an SMB (m) connector.
Option 310, Built-In Power Meter
Option 310 provides the functionality to make user-definable channel power
measurements such as transmitter output power. By leveraging InstAlign
technology, FieldFox is able to make very accurate channel power
measurements.
