This topic applies to NA520xA PNA-X Pro models only.
This topic describes differences between the SCPI commands for N52xxB models and NA520xA models. Refer to the tables below.
See also, New Programming Commands for the NA520xA PNA-X Pro.
Existing path configuration commands are valid for NA520xA, but the paths are different. See Elements and Settings.
These existing pulse commands are valid for NA520xA, but accept n = [0..8] rather than n = [0..4]. The numeric values also have a resolution of 2 ns rather than 10 ns.

Return Type |
Description |
|
C&Q |
Numeric |
Sets the pulse delay. The amount of time before a new pulse begins. |
|
|
C&Q |
Numeric |
Sets the pulse delay increment. The delay increments with each pulse by the <value> amount. |
|
|
Q |
Numeric |
Returns the ADC delay for pulse measurements. |
|
|
C&Q |
Numeric |
Sets the time lag between the pulse drive signal and the actual RF output. |
|
|
C&Q |
Boolean |
Enables/disables modulator and ADC delays for pulse measurements. |
|
|
C&Q |
Boolean |
Sets whether to invert the polarity of the pulse. |
|
|
C&Q |
Character |
Sets and reads the device being controlled by the pulse generator output. |
|
|
C&Q |
Numeric |
Sets the pulse-period (1/PRF) for ALL pulse generators. |
|
|
C&Q |
Boolean |
Turns the pulse output ON and OFF. |
|
|
C&Q |
Numeric |
Sets the pulse width. The amount of time that the pulse is ON. |

C/Q |
Return Type |
Description |
|
C&Q |
Numeric |
Sets noise bandwidth: 800 KHz, 2 MHz, 4 MHz, 8 MHz, or 24 MHz For NA520xA, additional bandwidths 200kHz, 400kHz, 720kHz, 1MHz, 1.2MHz, 12MHz |
|
|
C&Q |
Numeric |
Sets 0/15/30 dB gain For NA520xA, additional -15 dB gain |
|
|
C&Q |
Character |
Sets the noise receiver (normal or dedicated noise) For NA520xA, this feature is not available. Receivers are the same. If a user does not have noise hardware, they have a choice of -15dB or 0dB gain. |
