What accounts for the 2 orders of magnitude time difference to acquire a Bode plot between Siglent and R&S scopes?

SDS2504X HD, 1.2.1.1


--- Quote ---Parameters: Simple, Single Sweep, Decade, 100-100KHz, 20 pts/dec, Int AWG

AWG output to CH1 with BNC cable, another BNC to BNC cable from CH1 to CH2.

Done the settings, let it run...
And then checking it three times because:

3:35min.... ;)

Setting, final measure.
Interesting:

10Hz-100Hz : 2:03min
100Hz- 1Khz : 1:04min
1Khz-100Khz : 28sec.

EDIT:

Didn“t start from 100Hz like mawyatt mentioned.
Here the time from 100Hz- 100Khz, new measured:

1:45min

See this other Bode related thread just started, my have some clues to the large time discrepancy between various Bode Implementations.

Hello,

PicoScope 5444A with FRA 4PicoScope 0.7.3b  100Hz-100kHz 20 steps/dec -> ~5sec

with best regards

Andreas
