When NORMAL measurement mode is selected, the uncorrected fre- quency domain data consists of 64K values. Only the frequency domain data corresponding to 1270–1650 wavelength (in vacuum) is returned (15,047 values). In FAST measurement mode, the data consists of 32K values of which 7,525 values are returned.

In NORMAL measurement mode, the frequency spacing between values is uniform and is equal to 3.613378 GHz. Note that the spacing between values is not uniform in wavelength units. The values returned are in ascending optical frequency.

The first value of the uncorrected frequency data corresponds to an optical frequency of 181.6915 THz (1650.008 nm). The last value of the uncorrected frequency data corresponds to an optical frequency of 236.0584 THz (1269.993 nm). For example, a laser line peak located at the 3,000th returned value has an optical frequency of:

frequency = 181,6915 THz + 2, 999(3,613378 GHz)

=192,5280 THz

or, 1557.137 nm (in vacuum).

When FAST measurement mode is selected, the frequency spacing between elements is uniform and is equal to 7.226756 GHz. Note the spacing between values is not uniform in wavelength units. The values returned are in ascending optical frequency. Only the frequency domain data corresponding to 1270–1650 wavelength (in vacuum) is returned (7,525 values). The first value of the uncorrected frequency data corresponds to an optical frequency of 181.6879 THz (1650.041 nm). The last value of the uncorrected frequency data corresponds to an optical frequency of 236.0620 THz (1269.974 nm). For example, a laser line peak located at the 1500th returned value has an optical fre- quency of:

frequency = 181,6879 THz + 1, 499(7,226756 GHz)

=192,5208 THz

or, 1557.195 nm (in vacuum).

If your program is aborted or interrupted after sending this query, the Agilent 86120C continues to process the data but does not place it in the output buffer. Because of the amount of data processed, the instrument will not respond to any new commands in its input buffer for up to 20 seconds.
