1
If int erconnect cables are used, they must be low-EMI shielded cables such as the following
Tekt ronix part numbers or their equivalents: 012-0991-01, 012-0991-02 or 012-0991-03 GPIB
Cable; 012-1213-00 (or CA part number 0294-9) RS-232 Cable; 012-1214-00 Centronics
Cable; or LCOM part number CTL3VGAMM-5 VGA Cable.

The performance criteria for when the instrument is subjected to the conditions described
above are def ined as follows:
A — ≤0. 2 division waveform displacement or ≤0.4 division increase in peak-to-peak noise
B — temporary, self-recoverable degradation or loss of performance is allowed, but no change
of actual operating state or loss of stored data is allowed
C — temporary loss of function is allowed provided that the function is self recoverable or can
be restored by the operation of the controls
3
Radiated emi ssions may exceed the levels specified in EN 61326 when this instrument is
connected to a test object.
4
USB mouse and keyboard only, performance criterion C. Normal USB keyboard or mouse
operation can be restored by unplugging and reconnecting the USB connector t o the
instrument.
FCC Radiated and conducted emissions do not exceed the levels specified in FCC47 CFR, Part 15,
Subpart B, for Class A equipment.
