Channel-emulation test planning

A condition is an input.
A decision needs evidence.

Use this checklist to define a comparable experiment around your actual radio chain. The checks stay in this browser session; nothing is submitted or stored by this page.

Before you compare

Eight checks.
One interpretable test.

0 / 8 checked

01Write the decisionWhat development or integration choice should this test support? Define the observation that would change that choice.02Declare the actual endpointsRecord UE/gNB/modem/core or application versions, architecture, interface and the direction of useful traffic.03Bound the RF pathIdentify UL/DL legs, reference planes, supported settings and any external conversion or calibration. Assign fixed setup and represented satellite contributions once.04Establish the baselineVerify the intended static arrangement and useful observation before changing the condition.05Declare one changing conditionName the profile or factor, held variables, time origin and sign convention. Make assistance, position/epoch inputs and any intended compensation mismatch explicit.06Name the measurement ownerSpecify the endpoint/instrument, clock relationship, units, packet/file identity, completion rule and observation window. Verify relevant applied RF behavior beyond the command log.07Make the comparison interpretableRetain exact configurations, profiles, raw observations and analysis/conclusions. Include incomplete outcomes and distinguish comparable programmed inputs from identical replay.08Bound the conclusionState the actual tested configuration, uncertainty/limits and the engineering decision. Keep illustrative, measured and reported results distinct.

Use your team's test record for configurations, decisions and raw evidence. This page is a planning aid, not an execution record.

Illustrative completed example

One question.
A bounded comparison.

No measured values are implied by this planning example.

Decision: Choose a receiver setting for a declared residual-frequency condition.
Setup: One identified UE/gNB pair with compatible conducted UL/DL paths, actual network assistance and external traffic records.
Baseline: Matched static condition with attachment, session and useful traffic verified.
Change: Compare receiver settings while applying the same supported, declared residual-offset case; hold the other recorded inputs constant.
Observe: Attach/recovery behavior and useful traffic from the actual endpoints, with aligned timestamps and a stated completion rule.
Conclude: Report the selected configuration and observed limits. Do not generalize the finding to every terminal or claim identical RF replay.

From a question to an evaluation

Start with the decision
your test needs to support.

Discuss your radio implementation, the condition you need to investigate and the observation that would help your team.
