Page 17: Main Screen
2.3 Main Screen 2.3.1 Mode Switch RWC2020A Interference Generator has four operating modes: LBT channel mode, LBT burst mode, single-tone mode, and dual-tone mode. It can be switched from one to another by changing OP_MODE in parameter setup of RWC5020A, which shall be connected with an RS-232C cable. An example screen of RWC5020A for controlling RWC2020A is shown in Fig 2.3. - Page 18 This parameter controls the status of RF TX output. PATH_LOSS The path loss can be measured between the RF port of RWC2020A and the RF port of DUT via an RF splitter. RWC2020A’s real output power will be increased by this value to compensate the path loss.
-
Page 19: Lbt Burst Mode
CH_POW_01 ~ 07 These parameters define the offset values for RF channels with respect to the reference power level. 2.3.3 LBT Burst Mode In LBT burst mode, two different power levels can be applied to all RF channels with different time intervals. -
Page 20: Single-Tone Mode
This parameter controls the status of RF TX output. PATH_LOSS The path loss can be measured between the RF port of RWC2020A and the RF port of DUT via an RF splitter. RWC2020A’s real output power will be increased by this value to compensate the path loss NORMAL_POWER This parameter defines the power level of normal state which will be applied to all channels. -
Page 21: Dual-Tone Mode
This parameter controls the status of RF TX output. PATH_LOSS The path loss can be measured between the RF port of RWC2020A and the RF port of DUT via an RF splitter. RWC2020A’s real output power will be increased by this value to compensate the path loss. - Page 22 This parameter controls the status of RF TX output. PATH_LOSS The path loss can be measured between the RF port of RWC2020A and the RF port of DUT via an RF splitter. RWC2020A’s real output power will be increased by this value to compensate the path loss.
- Page 23 This parameter defines the frequency offset of the second signal relative to the FREQ1. FREQ2 This parameter indicates the frequency of the second signal (display only).

Page 24: Information Screen
2.4 Information Screen RWC2020A provides an additional information screen for users’ conveniences, which will be displayed by pressing the FN key on the rear panel. It shows its serial number, the IP address, and the firmware version. Moreover, the IP address is configurable remotely by RWC5020A. -
Page 25: Ethernet Ip Setup
2.5 Ethernet IP Setup Upgrading of RWC2020A firmware is only available through Ethernet interface, so IP configuration must be done before upgrading. IP configuration of RWC2020A is shown in RF parameter screen of RWC5020A as “IP_TYPE” and “IP_ADDR”. “IP_TYPE” parameter can be set to DYNAMIC or STATIC; DYNAMIC means that IP address may be obtained from the DHCP server automatically, and this configuration is recommended for RJ45 connection to a network hub. -
Page 26: Firmware Upgrade
2.6 Firmware Upgrade As RWC2020A adapted Flash Memory, it is available to upgrade easily by using a remote PC without changing the hardware. For upgrading, ‘RWC_Upgrader’ program shall be used, which is provided together when the product is purchased or available to download the upgrade package including itself and the upgrade binary files from RedwoodComm website (http://www.redwoodcomm.com). - Page 27 1) If Normal Firmware Upgrade Procedure fails during upgrading, the internal memory may be damaged. In this case, RWC2020A may not boot correctly. Then RWC2020A must be upgraded in Emergency Upgrade Mode. 2) Turn off RWC2020A. While keeping FN key on the rear panel pressed, turn on RWC2020A. Then...
- Page 28 RWC2020A will boot in Emergency Upgrade Mode as the following figure. 3) Make direct connection between a remote PC and RWC5020A using a crossover cable and wait until IP address of RWC2020A will be displayed on the screen. 4) Follow the steps 3) to 6) of Normal Firmware Upgrade Procedure.
