Keysight (Agilent) 70841B Pattern Generator, MMS

The HP 70841B Pattern Generator Module occupies 4/8 MMS module slot and has eight Input/Output ports, six on the front panel and two on the rear panel. A floppy disk drive enables the user to store user defined patterns up to 4 Mbits in length. Operating Frequency Range: 100 Mbit/s to 3 Gbit/s. Patterns: PRBS, zero substitution/variable mark density test patterns, and word test patterns. Four internal user pattern stores capable of holding up to 8192 bits, and eight disc pattern stores capable of storing up to 4 Mbits of data are provided. Alternate between two user-programmable 16-bit words under the control of the rear-panel Auxiliary input; changeover is synchronous with the end of the word. Switch between two data patterns (A and B), for example from (A to B) or (B to A). Enable a single insertion of a number of instances of pattern B to be output. The number of B instances is equal to the smallest integral multiple of the pattern length, that divides exactly by 128. Patterns A and B must be as follows: The same length and 1 bit to 2 Mbits in length. The rear panel ERROR INJECT input adds a single error to the data output for each rising edge (TTL levels) at the input. When a pure PRBS is selected (2 ^n-1), the TRIGGER OUTPUT produces a pulse which is either synchronized to the pattern (Pattern mode) or is the input clock divided by 32 (Clock/32 mode). Measure the incoming clock frequency to five significant digits. If an integral MMS clock source is used (for example HP 70311A or HP 70312A) then the frequency set up on this clock is displayed to ten significant digits. Specifications for the Clock Input, Data Output and Clock Output ports, and Trigger Output are given in the HP 71600B Series Installation and Verification manual. The rear panel AUX INPUT port can be used to control alternate patterns, alternate words or inhibit data.

Extinction Ratio
Extinction ratio is the ratio of two optical power levels, of a digital signal generated by an optical source, where P1 is the optical power level generated when the light source is "on," and P0 is the power level generated when the light source is "off." The extinction ratio may be expressed as a fraction, in dB, or as a percentage. Extinction ratio = P1/P0

A receiver is a detector and electronic circuitry to change optical signals into electrical signals.

Telecom Bands
Optical fiber communications typically operate in a wavelength region corresponding to one of the following Bands. O Band (original): 1260–1360 nm. E Band (extended): 1360–1460 nm. S Band (short wavelengths): 1460–1530 nm. C Band (conventional): 1530–1565 nm. L Band (long wavelengths): 1565–1625 nm. U Band (ultralong wavelengths): 1625–1675 nm
