WARNING **GENERAL**

If this product is not used as specified in the operating instructions, the protection provided by the equipment could be impaired. This product must be used in a normal condition (in which all means for protection are intact) only. Any external connections must be made prior to applying power.

WARNING **DO NOT REMOVE THE INSTRUMENT COVER**

No operator serviceable parts inside. Do not install substitute parts or perform any unauthorized modifications to the instrument. Return the instrument to Keysight for service and repair to ensure the safety features are maintained in operational condition. Instruments that appear damaged or defective should be made inoperative and secured against unintended operation until they can be repaired.

GROUND THE INSTRUMENT

This is a Safety Protection Class I Product (provided with a protective

earthing ground incorporated in the power cord). The mains plug shall only be inserted in a socket outlet provided with a protective earth contact. Any interruption of the protective conductor inside or outside of the product is likely to make the product dangerous. Intentional interruption is prohibited. The mains wiring and connectors shall be compatible with the connector used in the premise electrical system. Inadequate earth grounding can damage the instrument. Always use the three-prong AC power cord supplied with the instrument.

Connect the AC power cord as follow:

– Ensure that the power cord is not damaged.

• Install the signal generator so that one of the following items is readily identifiable and easily reached by the operator: AC power cord, alternative switch or circuit

Insert the mains plug into a socket outlet provided with a protective

earth groundin WARNING **IN CASE OF DAMAGE**

Do not use the instrument if it is damaged. Before you use the instrument inspect all connections. Pay particular attention to the insulation surrounding connectors and / or cable assembly insulation. NEVER use a cable showing any signs of damage. Faulty cables can cause electrical shock and /or fire hazards and could lead to personal injury or death.
Refer to the User Guides of the 34980A and relevant modules before using the equipment.

The detachable power cord is the instrument disconnecting device. It disconnects the mains circuits from the mains supply before other parts of the instrument. The front panel switch is only a standby switch and is not a LINE switch (disconnecting device). The instrument power cord does not disconnect or de-energize external circuits connected to the analog bus, terminal blocks or modul
Safety of any system incorporating the equipment is the responsibility of the assembler of the system.
Keysight Customers utilizing the Open Platform Test Systems are classified as follows and require the user to have the appropriate skillset:

Operator : Interacts with the test system in a production environment, selection of test sequences, defining variables, running tests (test results, test statistics, control of marking devices)

Dangerous voltage levels capable of causing death, may be present on a channel. Use extreme caution when handling and testing and adjusting this instrument. Any voltages greater than 30 Vrms, 42.4 Vpeak and 60 Vdc are considered hazardous (IEC 61010-1).

Removal of the instrument’s cover is to be conducted by qualified personnel only. Only qualified, trained personnel who are aware of the hazards involved should remove instrument covers. Prevent operators from accessing any external circuits, test fixtures, cables or wherever hazardous voltages may be present. Failure to recognize and observe normal safety precautions could result in personal injury or death.

ENVIRONMENTAL HEALTH & SAFETY: When any channel is connected to a hazardous voltage source, the instrument and the device under test should be supervised, following local EHS practices to restrict access.

34952A Multifunction Module

The 34952A Multifunction Module with DIO, D/A, and Totalizer combines four 8-bit ports of digital input/output, a 100 kHz totalizer, and two ±12 voltearth-referenced analog outputs. You can include digital inputs and totalizer input in a scan list. You can make connections via standard 50-pin D-sub cables or the optional 34952T terminal block.

Digital Input/Output

The Digital Input/Output (DIO) consists of four 8-bit ports with TTL- compatible inputs and output. The open-drain outputs can sink up to 400 mA. From the front panel, you can read data from only one 8-bit input port at a time. You can configure the DIO ports for 8, 16, or 32-bit operations. The DIO channels are connected by internal 5 V pull-up resistors when configured as inputs.

Totalizer Input

The 32-bit totalizer can count pulses at a 100 kHz rate. You can configure the totalizer to count on the rising edge or falling edge of the input signal. A TTL high signal applied to the Gate terminal enables counting and a low signal disables counting. A TTL low signal applied to the Not-Gate terminal enables counting and a high signal disables counting. The totalizer counts only when both terminals are enabled.
When a gate is not connected, the gate terminal is pulled to the enabled state, effectively creating a “gate always” condition.

Analog Output (DAC)

The two analog outputs are capable of outputting voltages between ±12 volts with 16 bits of resolution. Each DAC channel is capable of 10 mA maximum current. Use the two analog outputs to source bias voltages to your DUT, to control your analog programmable power supplies, or as set points for your control systems. The outputs are programmed directly in volts.

34952A SCPI Programming Examples

The programming examples below provide you with SCPI command examples to use for actions specific to the general purpose switch modules.
The slot and channel addressing scheme used in these examples follow the form sccc where s is the mainframe slot number (1 through 8) and ccc is the channel number. For information on specific configurations, refer to the simplified schematic on page 18For complete information on the SCPI commands used to program the 34980A, refer to the Keysight 34980A Programmer’s Reference which can be downloaded from www.keysight.com/find/34980A.

Digital Input/Output

Example: Configuring a DIO channel  The following program segment configures channel 1 on the DAC module in slot 3 as an output and then reads the output value (the channel is not reconfigured as an input). Then, the channel is reconfigured as an input and the value is read again.
The second command below returns 64 as it is physically reading the output data.
SOURce:DIGital:DATA:BYTE 64,(@3001) SENSe:DIGital:DATA:BIT? 0,(@3001)
The second command below returns whatever is being input externally.
CONFigure:DIGital:STATe INPut,(@3001) SENSe:DIGital:DATA:BIT? 0,(@3001)

Totalizer

Example: Reading totalizer channel count  The following command reads the count on totalizer channel 5 on the Multifunction module in slot 3.
SENSe:TOTalize:DATA? (@3005)
Example: Configuring the totalizer reset mode To configure the totalizer reset mode, send either of the following commands.
The following command configures totalizer channel 5 on the Multifunction module in slot 3 to be read without resetting its count.

SENSe:TOTalize:TYPE READ,(@3005)

The following command configures totalizer channel 5 on the Multifunction module in slot 2 to be reset to “0” after it is read (RRESet means “read and reset”).

CONFigure:TOTalize RRES,(@2005)

Example: Configuring the totalizer for count This command configures the totalizer to count on the rising edge (positive) or falling edge (negative) of the input signal. The following command configures the totalizer (channel 5) on a Multifunction module in slot 3 to count on the negative edge (falling) of the input signal.

TOTalize:SLOPe NEGative,(@3005)

Example: Clearing count on the totalizer channel This command immediately clears the count on the specified totalizer channels. The following command clears the count on the totalizer (channel 5) on a Multifunction module in slot 3.

TOTalize:CLEAR:IMMediate (@3005)

DAC Output

Example: Setting output voltage  This command sets the output voltage level for the specified DAC channels. The following command outputs +2.5 V DC on DAC channels (6 and 7) of a Multifunction module in slot 4.

SOURce:VOLTage 2.5,(@4006,4007)

Configuring a Multifunction Module

Example: Querying the system for module identify The following command returns the identify of the module installed in slot 7.
SYSTem:CTYPe? 7
Example: Resetting module(s) to power-on state The following command resets a module in slot 4 to its power-on state.
