Measure Match

NOTE: If an out of range value is entered, the minimum (if under-range) or maximum (if over-range) value will be substituted. If a maximum value that is lower than the minimum value is entered, the cursor will blink again on the minimum value waiting for a correct entry. The actual range depends on the units selected.

NOTE: Using the arrow keys will keep you in the acceptable range. If you are not sure if the larger value should be at the top or bottom of the scale, press the auto scale key to see where the software puts it.

Selecting the Sweep Type

Sweep types are continuous or single hold. Continuous will sweep and update the trace automatically. Single hold will sweep once and the trace will remain in the display. Each time single hold is pressed, the trace is updated.

yPress the MENU key.

yPress the SWEPT FREQ key.

yPress the SWEEP TYPE key.

yDepending on desired mode press either SINGLE HOLD or CONT key. HOLD will be displayed if single hold is selected. The tester begins sweeping if continuous is selected.

Saving a Trace

The AT-400 can store up to 12 traces. A saved trace can be used to evaluate long term antenna performance, compare performance under different conditions or for comparison to another antenna. A saved trace is also a powerful tool in limit testing (more about limit testing later in this section). The information can later be uploaded to a PC using optional interface software and the serial port. Traces are stored in nonvolatile memory so they are not lost when the Antenna Tester is turned off.

Since the reflection coefficient is the information actually saved when saving a trace, and everything else is calculated from that, you have some flexibility when using the trace for

AT-400 specifications

The Bird Brain AT-400 is a cutting-edge unmanned aerial vehicle (UAV) designed for versatility and performance in various applications such as surveillance, surveying, and environmental monitoring. This advanced drone incorporates state-of-the-art technologies and features that set it apart in the rapidly evolving drone market.

One of the standout features of the Bird Brain AT-400 is its exceptional flight stability and maneuverability. With a lightweight carbon-fiber frame, the AT-400 boasts an aerodynamic design that ensures efficient flight even in challenging weather conditions. The aircraft is equipped with advanced navigation systems, including GPS and inertial measurement units (IMUs), enabling it to maintain precise positioning and altitude control.

Powered by a high-capacity lithium-polymer battery, the AT-400 offers an impressive flight time of up to 45 minutes, depending on payload and environmental conditions. This extended operational time allows users to cover large areas without frequently returning to base for recharging.

The AT-400 is designed for modularity, allowing users to easily switch out payloads according to mission requirements. It can support various sensors, including high-resolution cameras, thermal imaging devices, and multispectral sensors for agricultural monitoring. This flexibility makes it ideal for industries such as agriculture, construction, and disaster management.

Another critical feature of the Bird Brain AT-400 is its advanced data transmission system. The UAV utilizes real-time video and data transmission capabilities, allowing operators to monitor live feeds and collect important information during flight. This system ensures that critical data is available immediately, enhancing decision-making processes on the ground.

Safety is a paramount consideration in the design of the AT-400. The aircraft is equipped with multiple redundancy systems, including dual electronic speed controllers and fail-safe mechanisms to ensure that it can safely return to base in the event of an emergency.

In terms of user experience, the Bird Brain AT-400 comes with an intuitive ground control station, featuring a user-friendly interface that simplifies mission planning and operation.

Overall, the Bird Brain AT-400 combines powerful performance with innovative technology and user-centric design, making it an excellent choice for both professional and recreational drone enthusiasts seeking reliability, efficiency, and adaptability in the field.
