Built In Test Unit (Bit)

With an aim to stand tall on the expectation of our honoured clients, we are devotedly engaged in manufacturer and supplier of Built In Test Unit (BIT) in Hyderabad , Telangana , India. We provide these product at market leading price to our customers. Offered these products are uses four DRO's selectively switchable through a frequency selection circuit. A 2-Bit logic is used for selecting the four DROs. The outputs of the DROs are selected through an SP4T Switch fed to a dual SPDT switch. The dual SPDTs select either a through path or an attenuated path to provide two levels of power output.
An SPST switch at the penultimate stage of BIT unit gives either pulse or CW signal. This switch is controlled by differential TTL. A high on this line makes SPST path through so that the unit gives CW output. A pulse command having a fixed pulse width of 1'S and a fixed PRI of 10 S, on this line gives pulsed RF output from the unit. An HPF is included in the circuit to avoid video leakage in RF output.
The RF circuit is realized in microstrip and embedded on a suitable carrier. The DROs are drop in type and are integrated to the RF circuit at four different input points on the RF circuit and the control card PCB is mounted on the RF circuit.
