3.

This sub-item includes accessories specially designed for microprocessor or microcomputer instruments or systems such as:

(4) "Cross-hosted" assemblers, "cross-hosted" compilers;

(6) Adapter interfaces for prototypes or emulation probes;

(c) Debuggers;

(d) Programmable read-only memory (PROM) programmers;

(e) Programmable read-only memory (PROM) copiers;

(f) So-called "personality" modules which contain more than one of the accessories enumerated under (a) to (e).

"Cross-hosted" compilers or "cross-hosted" assemblers, needed for use with a particular microprocessor or microcomputer development instrument or system not embargoed by this sub-item, must contain only the minimum "software" in machine executable form to perform the functions for which they were designed. To make other incompatible instruments or systems perform the same functions must require:

(a) Modification of this "software";

(b) Addition of "programmes".

4. For "cross-hosted" compilers or "cross-hosted" assemblers, which are not specially designed for use with microprocessor or microcomputer development instruments or systems described in this sub-item, see Item IL 1566.

(c) Digital counters, as follows:

(1) Capable of counting successive input signals with less than 5 nanoseconds time difference without prescaling (digital division) of the input signal (for counter/timers having a time interval measurement mode, see also (d) below);

(2) Employing prescaling of the input signal, in which the prescaler is capable of resolving successive input signals with less than 1 nanosecond time difference;

(3) Capable of measuring burst frequencies exceeding 100 MHz for a burst duration of less than 5 milliseconds;

(d) Time interval measuring equipment employing digital techniques, capable of measuring time intervals of less than 5 nanoseconds on a single shot basis;

(e) Testing equipment rated to maintain specified operating data when operating over a range of ambient temperatures from below -25°C to above +55°C;

(f) Digital voltage measuring Apparatus, with or without electrical outputs, irrespective of the physical units in which calibrated, with a reading speed (from zero to the measured value) faster than 25 accesses per second and having any of the following characteristics:

(1) A digital resolution at all points on the scale greater than one part in 200,000;

(2) An accuracy, measured without reference to an external standard, better than 1 part in 50,000 (0.002%) of reading over an ambient temperature range of +5°C or more, or a stability better than 10-6 of reading over a period of 24 hours or more;

(3) Capable of more than 500 independent measurements per second;

Notes:

1. Reading speed is assumed not to include changes in range or polarity.

2. This sub-item does not embargo-

(a) Visual quantization apparatus capable of providing an average value, displayed or not, of the results of the measurement;

(b) Multichannel analyzers of all types used in nuclear experimentation;

(c) Industrial telemeasuring devices in which a pre-set storage value is used as a basis for measuring.

(g) Transient recorders, utilizing analogue-to-digital conversion techniques, capable of storing transients by sequentially sampling single input signals at successive intervals of less than 50 nanoseconds.
