Description

This notification is in response to questions that came about from the previous synopsis, which appeared in the March 7, 2001 edition of the Commerce Business Daily. The following are the stated questions with the answer to each question: Question 1: The receive section clarify "Receive IF output power @ PldB+8dBm Minimum". Answer to Question 1: The government needs a minimum +8dBm of signal coming out of the receive IF port. Question 2: The transmit section, spectral regrowth, should QPSK be offset QPSK(OQPSK) for DSCS transmissions? Answer to Question 2: Yes, QPSK should be OQPSK. Its for X band. Question 3: The temperature range (-30 to+50C) is this operating? Is it the electronics operating temperature or just outdoor equipment such as antenna and IIPA? Answer to Question 3: This is operating temperature of all components. This is to be a portable unit where all components are outside. Question 4: The monitor and control section, what is "enable/disable time delay" referring too? Answer to Question 4: Enable/Disable Time Delay is a setting that is used to delay turning on the transmitter until the system has sufficiently warmed up and stabilized for proper transmission. Question 5: The monitor and control section, "Monitor Tx Frequency", is this monitoring the NRL modem frequency setting or do you want the offeror to supply equipment to sample and monitor the Tx RF? Answer to Question 5: Monitor Tx Frequency is monitoring the transmit frequency setting. When the status is requested, the unit will respond by sending the transmitter frequency setting over the serial interface. Question 6: What modem is NRL using and is it DSCS certified? Answer to Question 6: This modem is a unique design and any information is not necessary for this project. Question 7: The monitor and control section, are both RS-232 and R-485 ports required or can we supply just a RS-485 port? Answer to Question 7: The government requires an RS-232 port with a lower priority for an RS-485 port.
