<n> |
Pulse generator number. Choose from 1 to 4. 0 is the generator that pulses the ADC. |
<device> |
Pulse Device. Choose from: ADCTrigger - (Pulse0 only) Pulse 0 is used to trigger the ADC. RFMOdul - Iindicates that the pulse signal is used to drive the RF modulator.

If you try to set more than one pulse generator output to RFMOdul, then the other one will be set to UserN (where "N" is the pulse generator number). ADCActivity - (Pulse4 only) Pulse4 can also be set to monitor ADC activity. This selection outputs a signal on Pulse4 when the ADC is active. This is the same as SENSe:PULSe4:OPTion. USR1 through USR4 - Labels for user convenience. These labels do not connect the pulse generator to any specific hardware. These selections may be used to control a DUT, DC biases, or other signals. |

Applicable Models: N522xB, N524xB (Read-Write) Sets the specific PULSe4 behavior to either “ALL" ADC ACTivity or "TRACe" ADC Activity, WHEN Pulse4 has been set to display ADC activity using the SENSe:PULse4:OPTion command. “ALL” ADC Activity enables PULSe4 to indicate all ADC activity, even ADC measurements that are not displayed as final trace data. An example are background measurements used for receiver leveling, but that are never displayed on a trace. “TRACe” ADC Activity enables PULSe4 to indicate only the ADC activity that ends up displayed in a VNA trace. |
