1.) Type “sendfile <ENTER>” at the terminal. The unit will then initiate erasure of the
on-board flash. This erasure process will take approximately 1 minute.
2.) Once erasure is complete, the terminal will prompt “send file.” The device will then
send an initiate character to the terminal once every 10 seconds until the file is sent.
(NOTE: this process can be aborted by typing “Ctrl-C <ENTER> <ENTER>” but
the flash will remain empty.)
3.) To send the file, select “Transfer” from the menu bar, followed by “Send File…”.
4.) Browse to the bit pattern file desired, and then select “Xmodem” from the Protocol
list.
5.) Click “Send”. The file will then be transferred to the device.
6.) Once transmission is complete, the Xmodem transfer window will close and the
device will send a termination character to the terminal once per second.
7.) Type “<ENTER> <ENTER>” to exit the transfer routine.
4399A Commands:
Note: The following commands are case-sensitive.
deviceid: reads and returns the rev number of the board.
sendfile: erases the flash memory and waits for the input of a new BPSK file. The BPSK file is
transmitted via XMODEM. If a BPSK signal is running when this command is issued, the signal
output will be stopped.
freq: used to set the carrier frequency of the BPSK signal. After “freq <ENTER>” is typed, the
terminal will prompt for the frequency. Frequency is entered in MHz, in hexadecimal format (i.e.
1500 MHz will be entered as “5DC”). Valid frequencies are 900 MHz – 1175 MHz, 1225 MHz –
1575 MHz, and 1625 MHz – 1750 MHz.
chiprate: used to set the rate at which the BPSK bits are transmitted. After “chiprate <ENTER>”
is typed, the terminal will prompt for the chip rate. Chip rate is entered in MCPS, in hexadecimal
format (i.e. 10 MCPS will be entered as “a”, and 20 MCPS will be entered as “14”). Valid chip
rates are 1 MCPS – 20 MCPS.
run: used to reinitialize the signal output with the current frequency and chip rate settings.
stop: used to disable the signal output.
The following is a sample instruction set to initialize and run the 4399A unit at a frequency of 1
GHz, with a chip rate of 16 MCPS:
