HP FET MULTIPLEXER E1351A/53A manual Example Query Scan Mode

Page 67

SCAN:MODE [ROUTe:]SCAN:MODE <mode> sets the multiplexer channels defined by the [ROUTe:]SCAN <channel_list> command for None, Volts, 2-Wire Ohms, or 4-Wire Ohms measurements.

Parameters

Parameter Name	Parameter Type	Range of Values

mode	Discrete	NONE VOLT RES FRES

Comments ∙ Order of Command Execution: The [ROUTe:]SCAN:MODE command must be executed before the [ROUTe:]SCAN <channel_list> and [ROUTe:]CLOSe <channel_list> commands.

∙NONE and VOLT Mode Description: When selected, channel list is set up for volts measurements.

∙RES Mode Description: When selected, channel list is set up for 2-wire ohms measurements. The current source on I+ and I- is superimposed on the channel being measured. Appropriate tree isolation switches are automatically closed.

∙FRES Mode Description: When selected, channel list is set up for 4-wire ohms measurements. Specify only the channel on which the voltage is to be measured. The paired channel (plus or minus eight channels away) on the other bank will automatically close. If you specify both channels (@102, 110), the module will first setup for FRES reading on 02, then setup for FRES reading on 10.

∙*RST Condition: [ROUTe:]SCAN:MODE NONE

Example Selecting the 4-Wire Ohms Mode. This example scans 8 channels for 4-wire ohms resistance measurements.

TRIG:SOUR EXT	Selects external trigger source.
SCAN:MODE FRES	Selects the 4-wire ohms scanning
	mode.
SCAN (@100:115)	Sets channel list.
INIT	Starts scanning cycle.

SCAN:MODE? [ROUTe:]SCAN:MODE? returns the current state of the scan mode. The command returns NONE, VOLT, RES, or FRES if the scan mode is in the NONE, VOLT, RES, or FRES mode, respectively.

Example Query Scan Mode

This example selects the 4-wire ohms measurement mode (FRES), then queries the measurement state. Because 4-wire ohms mode is selected, the query command returns FRES.

SCAN:MODE FRES	Selects the 4-wire ohms scanning
	mode.
SCAN:MODE?	Query the scanning mode.
