These a re the primary outputs from the unit. The outputs can be used single-ended or differentially. Data pattern, levels and timing can be controlled manually or remotely.

These differential outputs provide a timing reference for viewing the data signals. The output amplitudes are ﬁxed. Trigger options are PATTERN or CLOCK/N.

When using a pattern trigger, the trigger corresponds to the beginning of a pattern. The pattern trigger mode can be used with user-deﬁned or PRBS data. For the CLOCK/N trigger mode, the clock frequency is reduced by a factor of N where

The clock output reﬂects the data rate; there is one full clock cycle per bit of data. The clock output is AC coupled and the amplitude is ﬁxed. The internal clock

ually operates over a range of 15 GHz to 30 GHz (PPG3000 series) or 16 GHz

act to 32 Ghz (PPG1600 and PPG3200 series). When data rates <15 Gb/s (PPG1600 and PPG3000 series) or <16 GHz (PPG3200 series) are used, the internal clock will operate at a multiple of the data rate and bit-stretching is used to produce data at the speciﬁed rate. A built-in clock divider can be used to divide the internal clock before it is sent to the clock output (divisors of 1, 2, 4, 8, 16).

This is the input used to supply an external clock. Clock frequency is restricted to a range of 15 GHz to 30 GHz (PPG3000 series) or 16 GHz to 32 GHz (PPG3200 series)—same as the range of the internal clock source.

NOTE. The external clock input is not available for the PPG1600 series.

|3|4]:PATTern:DATA

Set & Query

<start address> is numeric, and is the bit number in pattern data memory of the ﬁrst bit to write.

<bit count> is the number of bits to write into pattern data memory.

<data> is an arbitrary block of program data as de ﬁned in IEEE-488.2-1992, section 7.7.6.2. It starts with a "#" character, followed by a single character representing the length of the length, then 1 to 5 characters specifying the length as a decimal number, then the program data.

None

Programs the pattern data memory. Each byte of pattern data is a character (0 or 1) representing one bit of pattern data. The start address can be any bit location, 1 – < max address>. <max address> is > is 4,194,304 for one-channel instruments and 2,097,152 for a two-channel and four-channel instruments. The bit count can be any number 1 – 1024. The entire pattern data memory is accessible for reads or writes, even outside the range of the current pattern length setting. The bit count parameter and the length of the data block must match. (<start address> + <bit count>) must be ≤ (<max address> + 1).

:DIG1:PATT:DATA 1,16,#2160100000101010010

This command does the following:

Starts loading the Ch 1 data into bit location 1. Speciﬁes that 16 bits of data will be loaded. In the <data>:

#: signiﬁes the beginning of the block 2: indicates that the length of the data length is two characters 16: indicates that data length is 16 bytes. (16 ASCII characters) 0100000101010010: is the character representation of the data

Thus, bits 1 through 16 in the channel 1 pattern data memory will be set to 0100000101010010.

:DIG1:PATT:DATA? 1,8

This query reads 8 bits of channel 1 pattern data starting from address 1. Given the above pattern data memory contents, the response would be "#1801000001".

Set & Query

<start address> is numeric, and is the b it number in pattern data memory of the ﬁrst bit to write.

<bit count> is the number of bits to write into pattern data memory.

<data> is an arbitrary block of program data as deﬁned in IEEE-488.2-1992, section 7.7.6.2. It starts with a "#" character, followed by a single character representing the length of the length, then 1 to 5 characters specifying the length as a decimal number, then the program data.

None

Programs the pattern data memory using hexadecimal character format. Each byte of pattern data is a hexadecimal character (0-9, A-F or a-f) representing four bits of pattern data. The start address can be any bit location, 1 – <max address>. <max address> is 4,194,304 for one-channel instruments and 2,097,152 for a two-channel and four-channel instruments. The bit count can be any number 1 – 4096. The entire pattern data memory is accessible for reads or writes, even outside the range of the current pattern length setting.

The bit count parameter must be equal to 4 times the length of the data block or up to 3 bits fewer. If it is fewer, then the extra bits in the last data byte are ignored. (<start address> + <bit count>) must be ≤ (<max address> + 1).

:DIG1:PATT:HDAT 1,16,#144152

This command does the following:

#: signiﬁes the beginning of the block 1: indicates that the length of the data length is one character 4: indicates that data length is 4 bytes. (4 ASCII characters) 4152: is the character representation of the data

Thus, bits 1 through 16 in the channel 1 pattern data memory will be set to 0100000101010010.

:DIG1:PATT:HDAT? 1,8

This query reads 8 b its of channel 1 pattern data starting from address 1. Given the above pattern data memory contents, the response would be "#1241".

Note that if the query requests a number of bits that is not a multiple o f 4, some bits in the last byte will not be meaningful, and will be 0.

Preventive maintenance

Preventive maintenance mainly consists of periodic cleaning. Periodic cleaning reduces instrument breakdown and increases reliability. Clean the instrument as needed, based on the operating environment. Dirty conditions may require more frequent cleaning than computer room conditions.

Clean the ﬂat panel display

The ﬂat panel display is a soft plastic display and must be treated with care during cleaning.

CAUTION. Improper cleaning agents or methods can damage the ﬂat panel

display.

Do not use abrasive cleaners or commercial glass cleaners to clean the display surface.

Do not spray liquids directly on the display surface.

Do not scrub the display with excessive force.

Avoid getting moisture inside the instrument while cleaning the display; use only enough solution to dampen the wipe.

Clean the ﬂat panel display surface by gently rubbing the display with a cleanroom wipe (such as Wypall Medium Duty Wipes, #05701, available from Kimberly-Clark Corporation).

Clean the exterior surfaces

54 PPG1600, PPG3000, & PPG3200 Pattern Generator User Manual

Clean the exterior surfaces with a dry, lint-free cloth or a soft-bristle brush. If dirt remains, use a cloth or swab dampened with a 75% isopropyl alcohol solution. A swab is useful for cleaning in narrow spaces around the controls and connectors. Do not use abrasive compounds on any part of the instrument.

To avoid damaging the instrument follow these precautions:

Avoid getting moisture inside the instrument during external cleaning and use only enough solution to dampen the cloth or swab.

Do not wash the front-panel power switch. Cover the switch while washing the instrument.

Use only deionized water when cleaning. Use a 75% isopropyl alcohol solution as a cleanser and rinse with deionized water.

Do not use chemical cleaning agents; they may damage the instrument. Avoid chemicals that contain benzene, toluene, xylene, acetone, or similar solvents.
