38. The default mode for allocation of capture memory is AgM9391MemoryModeNormal, where the digitizer’s memory is shared by both the default single
acquisition (capture ID = 0) and all the other acquisitions with non-zero capture IDs. In particular, the memory for the default single acquisition is allocated
from the area unused by the list acquisitions. If the available memory is not sufficient for the single acquisition, the user must release memory allocated for
the non-zero capture ID acquisitions manually, thus increasing free space. Total memory usage is limited according to the memory option. Note that the
maximum size of acquisition is 2 GB in this mode. To perform the default single acquisition with memory size larger than 2 GB, AgM9391MemoryModeLar-
geAcquisition must be selected. The non-zero capture ID acquisitions cannot be performed in this mode. All data acquired with AGM9391MemoryMode
Normal will be invalidated.
39. The maximum size for a single list point capture is limited to 512 MSamples (2 GB). However, with option M10, total capture of up to 3.999 GB is available
across all list mode captures.
40. 64-bit mode, 2 samples for 32-bit mode.
41. Negative trigger delay limited to capture size.
42. Multi-channel capability only supported with up to 4-channels when configured with a Keysight M9018A PXIe chassis with FPGA version 1.05 or greater.
Characteristics measured at 400, 900, 2400, 5800 MHz and apply in auto conversion mode at frequencies ≥ 400 MHz with IF filter = 160 MHz.
43. Jitter indicates measurement-to-measurement variation and applies over short time interval at room temperature without resetting or reinitializing a driver
session.
44. Repeatability indicates stability of alignment between channels across power cycles and IVI sessions, with identical cabling and hardware settings (fre-
quency, span, sample rate, etc.)
45. Channel time and phase offsets can be adjusted using OffsetDelay and OffsetPhase properties respectively.
