in turn drives the clock input of the HSP45116. The jumper

inserted between JA2 and SA2 allows the Input Header’s

CLK_IN pin to be driven by the buffer output.

NOTE: The

jumper placement shown in Figure 5 is the standard

configuration..

The HSP45116-DB is shipped from the factory with the

default jumper configuration shown by the overlay of heavy

lines onto the signal map in Table 1. For the Control Panel

and Command Line Interface software to properly control

operation of the HSP45116, it is assumed that the

HSP45116 control inputs are jumpered as specified in the

default configuration. Also, the system test software,

NCOM_CHK, must be run using the default configuration.

Data File Structures

The Input/Output data files used by the HSP45116-DB

Control Panel and Command Line Interface software contain

complex data samples. The data files consist of a seven line

header followed by the data itself. The header section must

follow this format:

Line 1:

Comment #1

Line 2:

Comment #2

Line 3:

Comment #3

Line 4:

Line 5:

Comment #6

Line 7:

The ‘n’ on the 7th line of the header should be replaced by

the number of complex samples in the file. Following the

header, the complex samples are listed one per row with the

real part listed first followed by the complex part. The real

and imaginary components of the complex data sample are

represented as 16-bit two’s complement values. As a result,

the real and imaginary parts of the data sample are integer

values bounded by 32767 and -32768. The CMPRFILE

installed in the NCOM_CHK subdirectory is an example of

the input data file structure.
