Still to measure

What we have not measured yet, on every scope family, and what each test is waiting on. A test that is done goes on its family's NovaOS vs stock page, with its date, its method and its raw data, and leaves this list. Nothing here has a date: each is measured once what it waits on is in place.

CH1Rigol DHO800/DHO900 and MHO900

The MHO900's waveform rate with NovaOS, counted from outside the scope the same way as on the stock firmware being measured
- MHO934: waveforms a second, CH1 alone at 20 ns/div, clean scene: NovaOS
The stock firmware's waveform rate on the MHO900, its cost of one measurement item and of its own counter, measured again being measured
Why the stock firmware's waveform rate on the MHO900 reads lower on one channel than on another with the same signal being measured
Idle writes to the MHO900's internal storage on the stock firmware, NovaOS and Kiszka's mod, measured the same way being measured
- MHO934: storage writes while idle: Rigol's firmware
- MHO934: storage writes while idle: Kiszka's mod v0.1.5
For each scene, what the MHO900's hardware allows: the FPGA's frame period, the readout limit, the waveforms counted and the screen's pictures a second not started yet
The shared-buffer path from the acquisition to the screen, measured on the NovaOS image that ships waiting for the next NovaOS image
The MHO900's step response at its 1 MOhm input with NovaOS, and an equaliser for that input built from it waiting for the pulser and its feed-through to be moved to the NovaOS scope
One pulser edge split to three MHO900s at once, so the stock firmware, NovaOS and Kiszka's mod see the same step at the same time waiting for parts
Kiszka's mod v0.1.5 on the MHO900: the rows of its column not measured yet not started yet
- MHO934: what one measurement item on the screen costs (1k): Kiszka's mod v0.1.5
- MHO934: what counting on the scope's own CH4 costs: Kiszka's mod v0.1.5
- Auto band limit: the band follows the sample rate: Kiszka's mod v0.1.5
- Interpolation on the screen: Auto, Linear or sin(x)/x: Kiszka's mod v0.1.5
- ARINC 429 and SENT decoding: Kiszka's mod v0.1.5
- Step response with a fast-edge pulser on the scope's USB: Kiszka's mod v0.1.5
Kiszka's mod v0.2 on the MHO900: the waveform rate its author publishes, counted by us waiting for the author's release
Time-base accuracy against a GPS-disciplined reference on the MHO900s and the DHO, with our free SCPI-only kit waiting for a GPS fix and cables
The DHO with NovaOS: every test that needs a signal, the waveform rate, the step response, the density display and Auto waiting for a cable from the signal generator to the scope
Auto finding a connected signal on every channel, shown live on the scope waiting for a fix to land
The measurement strip on the screen against the same measurements read over SCPI, on a live signal waiting for a fix to land
Power-on time, RAM in use, network transfer rate and idle storage writes on the DHO and the MHO900, on both systems not started yet
A current probe on a channel set to amperes, read end to end against a known current: the DHO with NovaOS waiting for the probe to be wired
A current probe on a channel set to amperes, read end to end against a known current: the MHO900 with NovaOS waiting for the probe to be wired
A current probe on a channel set to amperes, read end to end against a known current: the MHO900 with Rigol's firmware, the same steps waiting for the probe to be wired
A current probe on a channel set to amperes, read end to end against a known current: the MHO900 with Kiszka's mod v0.1.5, the same steps waiting for the probe to be wired

On the comparison page, also without a measurement:

MHO934: what one measurement item on the screen costs (1k): NovaOS, not yet counted from outside
MHO934: what counting on the scope's own CH4 costs: NovaOS, not yet counted from outside

CH2Siglent SDS800X HD

Siglent's own firmware on the SDS800X HD: its side of every comparison on that page, run the same way as NovaOS's waiting for the scope to be booted to its stock firmware
- Waveforms a second, by the scope's own acquisition count (:ACQuire:NUMACq?), 1 us/div, 10k points: Siglent's firmware
- Whole 10k-point records a second over SCPI (:WAVeform:DATA?): Siglent's firmware
- Answer time of :TRIGger:STATus?, 50 reads back to back: Siglent's firmware
- A screenshot over SCPI (:PRINt? PNG): Siglent's firmware
- SCPI round trip, 500 *OPT? queries back to back on one connection: Siglent's firmware
- Sustained *OPT? queries a second over 10 s: Siglent's firmware
- Remote screen (VNC on port 5900), frames a second over 10 s: Siglent's firmware
For each scene, what the SDS800X HD's hardware allows, measured the same way as on the MHO900 not started yet
Power-on time, RAM in use, network transfer rate and idle storage writes on the SDS800X HD, on both systems not started yet

CH3Owon ADS800A

The first comparison of NovaOS with Owon's own firmware on the ADS800A not started yet
For each scene, what the ADS800A's hardware allows, measured the same way as on the MHO900 not started yet
Power-on time, RAM in use, network transfer rate and idle storage writes on the ADS800A, on both systems not started yet

CH4Across families

The MHO900's acquisitions a second with NovaOS by its own count, measured the same way as the SDS800X HD's, for the side-by-side page not started yet
