:HVONset / query
Turns on the high voltage output, provided the front-panel HIGH VOLTAGE switch is not in the OFF position. If the switch is OFF, the output remains off and an execution error is reported; the command also clears any voltage or current trips.
*RSTset / query
Initializes the memory and loads the default setup. The manual describes this as a power-on reset performed by holding the CLR button while turning the unit back on.
*CLSset / query
Clears the instrument status registers and error queue.
*ESEset / query
Sets the standard event status enable register to the specified value. The command is also used as a query form (*ESE?) in the manual index.
| Name | Type | Values | Description |
|---|---|---|---|
| n | integer | 0 - 255 | Bit mask value for the event status enable register. |
*ESE?query
Sets the standard event status enable register mask. The command is the setter form of *ESE? and accepts an integer value.
| Name | Type | Values | Description |
|---|---|---|---|
| n | integer | 0 - 255 | Standard event status enable register mask. |
*ESR?query
Returns the contents of the Standard Event Status Register. The optional <n> qualifier can be used with the query syntax as shown in the index entry.
| Name | Type | Values | Description |
|---|---|---|---|
| nopt | integer | - | Optional qualifier for the query syntax. |
integer - Contents of the Standard Event Status Register.
*IDN?query
Returns the instrument identification string.
string - The instrument identification string.
*OPC?query
Indicates that all commands before *OPC? have been executed. The query returns a 1 when complete.
integer - Returns 1 when all pending operations are complete.
*PSCset / query
Sets the power-on status to be restored after a reset or power cycle. This is a common IEEE 488.2 common command and is listed in the interface control commands section.
| Name | Type | Values | Description |
|---|---|---|---|
| n | integer | - | Power-on status setting. |
*PSC?query
Sets or queries the power-on status clear mode. This command is documented as a paired setter/query form with an optional numeric argument.
| Name | Type | Values | Description |
|---|---|---|---|
| n | integer | 0 - 1 | Power-on status clear mode. |
integer - Returns the current power-on status clear mode.
*RCLset / query
Recalls a setup from nonvolatile memory.
| Name | Type | Values | Description |
|---|---|---|---|
| n | integer | 0 - 9 | Memory location to recall. |
*SAVset / query
Saves the current instrument state in the specified nonvolatile memory location.
| Name | Type | Values | Description |
|---|---|---|---|
| n | integer | - | Memory location to save the current state. |
*SREset / query
Sets or queries the service request enable register. The value determines which status bits can generate a service request.
| Name | Type | Values | Description |
|---|---|---|---|
| n | integer | 0 - 255 | Service request enable register value. |
*SRE?query
Sets or queries the service request enable register. The query form returns the current value of the register.
| Name | Type | Values | Description |
|---|---|---|---|
| nopt | integer | 0 - 255 | Service request enable register value. |
integer - Returns the current service request enable register value.
*STB?query
Returns the status byte. An optional numeric qualifier may be supplied in brackets in the syntax listing.
| Name | Type | Values | Description |
|---|---|---|---|
| nopt | integer | - | Optional status byte qualifier. |
integer - Returns the status byte.
*WAIset / query
