3-2 Operation
Introduction
This section contains detailed information on front panel and IEEE-488 bus operation of the
Model 2000-SCAN-20. The information in this section is organized as follows:
•
Signal limitations —
Summarizes the maximum signals that can be applied to the
Model 2000-SCAN-20.
• Scanner card detection — Discusses how the multimeter detects a scanner card and
how to use a bus command to determine whether or not a card is installed in the
multimeter and identify the type of card.
• Model 2000 multimeter front panel scanner controls and SCPI bus scanner
commands —
Gives an overview of the Model 2000-20 Multimeter front panel controls
and corresponding IEEE-488 bus commands used to control the scanner card.
•
SCPI scanner commands —
Summarizes the bus commands necessary to control the
scanner card using the Model 2000-20 Multimeter.
• Typical applications — Discusses typical applications for the Model 2000-SCAN-20.
• Measurement considerations — Discusses a number of measurement considerations to
take into account when using the scanner.
NOTE Before using the Model 2000-SCAN-20 scanner card, you should be thoroughly
familiar with the operation of the multimeter. See the multimeter manual for details.
Signal limitations
CAUTION To prevent damage to the Model 2000-SCAN-20, do not exceed the
maximum signal level specifications of the card.
Relay input signal limitations
Channels 1 through 20 are all relay inputs. To prevent overheating or damage to the relays,
never exceed the following maximum signal levels for these channels:
DC signals: 60V DC, 0.5A switched, 30VA (resistive load).
AC signals: 30V rms or 42.4V AC peak, 0.5A switched, 15VA (resistive load).
NOTE Model 2000-SCAN-20 is limited to non-hazardous voltages only.
