Configuration and supply

120 MHz requires bandwidth-extension option 073 and is not the default for every configuration. Real-time 068 and communications options 069/071/072 are software choices; select hardware bandwidth accordingly.
Direction finding 038 is built-in software but requires positioning 010, a USB compass and directional antenna. Map function 074 requires an external BNC GPS antenna. ZE9080 amplifier 025 includes a USB compass.
The full-band preamplifier is standard, with different noise specifications in on and off states. Nominal dimensions exclude side strap and rear support; weight excludes the battery.
Catalog supplied items are listed in the accessory table. Extra antennas, sensors, cases, software and calibration services are not all included by default. Confirm the actual supplied configuration in the quotation.
Warranty extensions exclude calibration; confirm service coverage and shipping terms. Provide band, signal standards, analysis bandwidth, real-time/IQ/direction-finding needs, reports and quantity.
