SOURce:MODule:CLOCk:LEVel
Syntax
SOURce:MODule:CLOCk:LEVel {<voltage>|MIN|MAX|DEF}, <slot>
SOURce:MODule:CLOCk:LEVel? [{MIN|MAX}, ] <slot>
Description
This command sets the logic "1" voltage level for external clock outputs on the 34950A Digital I/O Module in the specified slot. The external clock frequency is derived from the internal 20 MHz timebase clock on the module. Once enabled, the clock signal is output from Pin 62 on the module's D-Sub connector (connector P2).
Used With:
34950A Digital I/O Module

Numeric |
Desired voltage level between 1.66V and 5V, with 20 mV resolution. MIN = 1.66V, MAX = 5V |
1.66V |

<slot> |
Discrete |
{1|2|3|4|5|6|7|8} |

Remarks
To set the frequency of the external clock output, use the SOURce:MODule:CLOCk:FREQuency command.
To enable the specified clock signal to be output from the module, use the SOURce:MODule:CLOCk:STATe command.
A Factory Reset (*RST command), Instrument Preset (SYSTem:PRESet command), and Card Reset (SYSTem:CPON command) will disable the clock output and reset the voltage level to 1.66V.
Return Format
The query command returns the voltage level in the form "+1.00000000E+00". Multiple responses are separated by commas.
Examples
The following command sets the voltage level to 2.4V on the module in slot 3.
SOUR:MOD:CLOCK:LEVEL 2.4,3 !Logic "1" = 2.4V
The following query returns the voltage level setting on the module in slot 3.
SOUR:MOD:CLOCK:LEVEL? 3
Typical Response: +2.40000000E+00
