Recent news

July 20 2005 We will soon be introducing two new standalone frequency generators, the F165 and F125 and a circuit board only version F110 for system builders. For more information and pictures click: F165, F125 or F110.

From time to time, we get requests from users who want to write their own software to drive our generators. If you are interested in wirting your own software, you can find more information here


Previous news





F100 series function generators are highly programmable hardware devices that connect to your computer or Palm Pilot serial port. They are controlled by the F100 software running on the PC/Palm to output frequencies you program via text files or the user interface. The F100 software gives you full control over the frequency, duty cycle, sweep, loops, gating/modulation and many other parameters described in the user guide. Frequencies are not computer generated. The F100 hardware frequency generator module, external to the PC, generates precise, crystal referenced frequencies. The PC/Palm is only used to tell the F100 frequency generator module what frequency to output and for how long, basically replacing the knobs on the front of the generator and the need to turn them. Intended for any application that requires fully programmable frequencies.

Key features

Fully programmable frequencies.
    Individual frequencies
    Sweeps

Specifications

PC System requirements:
IBM PC compatible system
MS-Windows 95,98,Me,2000,XP,NT4.
16 MB ram
5 MB free hard disk space
One free RS-232 port capable of 19200 bps (most are). If no serial port is available, USB connection is also possible with a USB to serial adapter sold here.

Processor speed is not critical. We have tested it on Pentium 90 MHz with Windows 95. The only restriction is if you program frequencies to change hundreds of time per second. The 19200 bps RS-232 rate puts a limit on the number of frequency change per second to around 192. Which means the theoretical minimum dwell time is .005 seconds. But this can be higher if your CPU cannot keep up. If very small dwell time are critical for your application, you can easily test the response time by downloading the free software and timing a sweep with small dwell time on your system.

Software installation requires a CD-ROM drive or an Internet connection. If your system doesn't have those, contact us and we will provide you with diskette files.
