This is a simple Bash script to manage the frequency of a FE-5680A rubidium frequency standard. It can print the current frequency, set a new frequency, and persist the current freqency to NVRAM so that it is remembered if the unit's power is diconnected.
It may also work with other FE-56xx devices. I haven't investigated this.
Command-line usage can be obtained at any time with the -h, --help, or help arguments. You will see the output:
Usage:
fe5680.sh help
fe5680.sh --help
fe5680.sh -help
Print this help message
fe5680.sh device <dev> [opt] <cmd ...>
Execute command(s) on a given FE56xx serial device, where:
"device <dev>" specifies the serial device
[opt] is an optional argument:
"raw" print serial I/O from the device to stderr
<cmd> is one or more of the following:
"get" print the current frequency
"set N" set the frequency to N Hz
"write" write the current frequency to NVRAM
Example 1:
$ ./fe5680.sh device /dev/ttyUSB0 get
This prints the frequency of the FE-5680A device connected to serial port
/dev/ttyUSB0. It will output something like:
Frequency: 10,000,000.00 Hz
Example 2:
$ ./fe5680.sh device /dev/ttyUSB0 get set 10123000.1 get
This prints the frequency of the FE-5680A device connected to serial port
/dev/ttyUSB0, sets the frequency to 10,123,000.1 Hz, then prints the
frequency again. It will output something like:
Frequency: 9,999,999.80 Hz
Set frequency command succeeded.
Frequency: 10,123,000.10 Hz
