The low range of frequencies from 380kHz to 100MHz are generated by external binary dividers with ratios between 2 and 64. ECL dividers are used, with differential outputs. E6-SS Manual A5 29 September 2015 Page 7... - Page 8 1kHz or less on low range, or 3kHz on high range. For any CW frequency, the software attempts to use exact frequency mode. If successful, a front panel LED indicator is lit. In addition a status bit is set in an interface message. E6-SS Manual A5 29 September 2015 Page 8...
- Page 9 The total frequency shift is that programmed for internal FM deviation. i.e., a programmed deviation of 10kHz produces a frequency shift of ±5kHz. The maximum baud rate is about 35kbaud. If the maximum rate is exceeded, data bits will be skipped. E6-SS Manual A5 29 September 2015 Page 9...
- Page 10 This means that the external reference phase noise will directly affect the output phase noise over the range of the loop bandwidth, approximately 0Hz to 200kHz. E6-SS Manual A5 29 September 2015 Page 10...
- Page 11 LEDS are turned off to show that the memories may not reflect the current instrument status. The user memories store the CW frequency, RF level, modulation parameters, and the modulation mode. E6-SS Manual A5 29 September 2015 Page 11...
