Yellowjacket-BANG Wi-Fi Analyzer is a handheld, wireless test receiver system that demodulates, sweeps, analyzes, and optimizes all popular 802.11 Wi-Fi network standards including 802.11b/g (2.4 GHz), 802.11n, and even 802.11a 5 GHz). The calibrated receiver is a passive measurement device that is network independent so it remains “invisible” to any 802.11 Wi-Fi network.
Yellowjacket® B/A/N/G is also a powerful spectrum analyzer that measures RF energy (2.0-4.0 & 4.9-5.9 GHz) allowing not only detailed interference analysis but the ability to see the “whole picture” of your 2.4 and 5 GHz network WISP or hotspot. When equipped with a BVS DF (Direction Finding) antenna, Yellowjacket® B/A/N/G locates and pinpoints rogue APs and STAs and even detects interference from sources such as microwave ovens and cordless phones. Powerful packet analysis features such as Multipath (Ec/Io), SNR (Signal-to-Noise Ratio), Delay Spread, Channel Frequency Response (CFR), SSID and Received Signal Strength Indicator (RSSI) give Yellowjacket® B/A/N/G the distinction of being the only true handheld RF spectrum protocol analysis and direction finding tool accurate to within +1 dB. Yellowjacket® B/A/N/G functions as a complete WLAN analysis system offering both measurements made through packet demodulation and spectrum analysis in a rugged, handheld package.

For the following questions, “Unit” refers to your YellowJacket-BANG receiver module.
Battery life and protection: How Do I maximize battery run time and lifetime?
Recharge – Recharge your unit’s and Tablet PC’s batteries monthly. Keeping the unit permanently connected to the external charger power supply in NOT recommended.
Windows™ Power Settings – Check (under the Windows™ Control Panel’s Power Settings) that the Tablet PC is set to NEVER Sleep, Hibernate or Standby. A Tablet PC in Sleep, Hibernate or Standby cannot monitor the Unit’s battery.
Swarm Software Upgrade – Upgrade your Swarm Collector Software (if purchased with your YellowJacket unit) to v 1.04 or later. Earlier versions left the unit powered after the program was shutdown.
Communications: My unit is not communicating with the Tablet PC – what can I do?
1. Power your unit from the external AC power supply.
2. Check that the USB cable is connected between the Unit and the Tablet PC./
3. Unplug and plug the USB cable to verify that the USB Driver is installed.
4. Remove any Ethernet cables connected to the Unit. An Ethernet Cable connected to the Unit will disable USB communications.
5. Contact BVS Technical Support.
Battery Power not functional: My unit works properly from AC power, but is not operating from the internal Batteries – what can I do?
1. Reset the Battery Pack:
2. Power the Unit from the AC power supply.
3. Momentarily press (less than 1 second) the recessed Battery Reset Button (see your manual for exact location) on the bottom of the unit.
4. Remove the Unit’s connector to the AC power supply.
5. Repower the Unit from the AC power supply. The Green Status Light should “Flash”; if it does not “Flash” the above battery reset procedure may be tried for a maximum of 3 times.
6. Allow to charge for at least 1 hour and then try operating the Unit from battery power.
7. Contact BVS Technical Support for additional support.
Status Lights: The LED lights on the back of the Unit – What do they Indicate?
“ON” – Unit is on and able to communicate.
“OFF” – Unit is off and is NOT able to communicate.
“ON” – Unit is connected to external supply and fully charged.
“OFF” – Unit is not connected to external supply.
“Flashing” – Unit is connected to external supply and charging.
Shipping and unit care: How should I pack the Unit for shipping?
Ship the unit in the Factory supplied case with the supplied padding. Remove the USB connector from both the Unit and Tablet PC when shipping. Remove all antennas and power supplies connected to the unit and Tablet PC.
Windows™ Power Setting: How do I change Windows™ power settings?
1. Click on Start > Control Panel > System and maintenance > Power Options.
2. Click on “change plan settings” under the selected plan.
3. Change both sleep settings to never.
4.Next click “change advanced power settings”.
5. Expand “Power buttons and lid” in the list.
6. Expand “power button action” and change both to shut down.
7. Then expand “Start menu power button” and change both settings to shut down.
1. Click on Start > Control Panel > Power Options icon (in the classic view).
2. Set System Standby/Sleep/Hibernate to NEVER.
No Signals Detected: My YellowJacket-BANG is not Detecting any Signals in the DEMODULATION Screen – Help?
1. Check the Instrument’s Settings under the Display Devices Tab:
2. Select Channel Tab – verify that your frequency/channel is in the Channel List.
3. Check that your antenna/cable is properly attached and that the antenna/cable’s SMA male pin is not bent or missing.
No Signals Detected: My YellowJacket-BANG is not Detecting any Signals/Interferers in the SPECTRUM Mode – Help?
1. Check the Instrument’s Settings:
2. Center Frequency – verify that it is set to the center of your channel/signal.
3. Span – Verify that it is set to at least the span of your channel/signal.
4. Trace – Verify that at least 1 Trace is set to LIVE.
5. Trigger and Peak Hold: Many signals/interferers transmit only periodically and may be “on” for short amounts of time. Use the Trigger Mode or Trace Peak Hold to detect and measure these types of signals. See your manual for more details.
6. Reference Level: Adjust the Reference Level lower to detect weaker signals.
7. Check that your antenna/cable is properly attached and that the antenna/cable’s SMA male pin is not bent or missing.
