    MANUAL IM672 1. Safety Summary Definitions The following definitions apply to WARNINGS, CAUTIONS, and NOTICES may found throughout this manual. WARNING: An operating or maintenance procedure, practice, statement, condition, etc., which, if not strictly observed, could result in injury and/or death of personnel. Do not proceed beyond a WARNING symbol until all the indicated conditions have been fully understood and/or met.

  • Page 5: General Information

    Series. The manual also provides a description of the assembly and general maintenance procedures. Equipment Overview The 4205A series digital attenuators provide for control either via USB or a variety of digital interfaces via the AUX mode connector, including parallel input (PIO), I2C, SPI, or a logic-level UART interface. AUX mode selection is done via USB command and can be changed via the user.

    MANUAL IM672 Parameter Comments I2C mode SCL clock frequency 400KHz RESETN width 10us RESETN low pulse width (optional) TRIG TRIG input, rising/falling edge (optional) UART mode Baudrate 9600 115K DC Power Input The 4205A can be powered from either the USB VBUS (5V) or the AUX VDC input. While USB operates at a nominal 4.75V-5.25V range, the AUX VDC supply input can accept a wider range of voltage, from 3.3V-16VDC.

    Do not over torque the SMA connectors more than 10 inch pounds. Damage may occur. RF Connectors & Cable Installation The Model 4205A series contains two SMA female connectors labeled J1 and J2 that mate nondestructively with SMA male connectors per MIL-STD-39012. Weinschel recommends a torque value of 7 to 8 inch pounds when connecting any cable to the attenuator's RF connectors.

    MANUAL IM672 A device address can also be assigned using the USB SET I2CADDR command which allows the use of all 7 D7-D1 address bits, with the exception of the reserved address 0. A software assigned address overrides the hardware A3-A0 pins and connections to these pins are ignored.

  • Page 13: Pulse Mode

    MANUAL IM672 RF ON (0dB) RF LEVEL D0 = 0 D0 =1 RF OFF (MAX dB) 4.6.2 PULSE Mode PULSE mode allows the 4205A to generate a pattern of pulsed RF ON/RF OFF levels based on user settings. During the RF ON time the attenuation is set to 0dB, and during the RF OFF time the attenuation will be set to the max value.

  • Page 14: Usb Mode Aux Pin Usage

    MANUAL IM672 D0 pin can be used to supply a 1 if enable control is not required (see SET WPU), and is on by default. The FADE_STAT output will assert high when the RF output is ramping attenuation, and will be low otherwise. In order to change operation, once the parameters are set via the SET FADE commands you can switch from USB to AUX mode using the command RUN AUX.

For example, sending "*CLS;*OPC?" will place a "1" in the output queue when the *CLS command has been executed. Query commands that return multiple values will have the values separated by an ASCII COMMA character (0x2E). If multiple Query commands are included in the same message, the individual query responses will be separated with an ASCII SEMICOLON character (0x3B).
