|
instrument handle The instrument handle that you obtain from the IviDownconverter Initialize or IviDownconverter Initialize With Options VI. The handle identifies a particular instrument session.
Default Value: None |
 |
reference oscillator source (Internal) Pass the reference oscillator source used to generate the precise IF output frequency. The driver uses this value to set the IviDownconverter Reference Oscillator Source [RO] property.
Valid Values: IVIDOWNCONVERTER_VAL_REFERENCE_OSCILLATOR_SOURCE_INTERNAL - Internal reference oscillator. IVIDOWNCONVERTER_VAL_REFERENCE_OSCILLATOR_SOURCE_EXTERNAL - External reference oscillator. Default Value: IVIDOWNCONVERTER_VAL_REFERENCE_OSCILLATOR_SOURCE_INTERNAL |
 |
external frequency (10.0e6 Hz) Pass the frequency of the external signal that is used as reference for internal IF frequency generation. The driver uses this value to set the IviDownconverter Reference Oscillator External Frequency [RO] property.
Default Value: 10.0e6 Hz Notes: (1) This value is valid only when IviDownconverter Reference Oscillator Source [RO] is External. |
 |
error in (no error) The error in cluster can accept error information wired from VIs previously called. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs.
The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |
 |
instrument handle out The instrument handle that you obtain from the IviDownconverter Initialize or IviDownconverter Initialize With Options VI. The handle identifies a particular instrument session.
Default Value: None |
 |
error out The error out cluster passes error or warning information out of a VI to be used by other VIs.
The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |
