Creating a Test Plan - CE 234G
The CE 234G option is used for EU CE (RED) certification testing of cellular products (2G GSM / 3G WCDMA / 4G LTE), covering receiver tests in addition to transmitter tests. When creating a test plan, select the Type (technology) first; the form will show the corresponding options for the selected technology. Each technology is described separately below.
GSM
Title: Test plan name, entered by the user, e.g., GSM / B1 / LTE-Ant1.
Type: Technical category, select GSM here.
Band Info: Operating bands supported by the product, one band per row:
Band: Band name; EGSM900 / DCS1800 are available for European GSM. After selecting from the drop-down, the system automatically fills in the corresponding uplink frequency.
UL Frequency: Uplink frequency range (MHz) of the band, filled in automatically and editable.
TX Type: Transmission type, fixed to SISO.
Bandwidth UL: Uplink channel bandwidth, fixed to 0.2 (200 kHz) for GSM.
Action: Click the red delete icon to remove a band row; select a band from the bottom Select drop-down to add a new row.
Network: Network modes supported by the product, multi-select: GSM / GPRS / EGPRS. Select according to the product's actual support; the Item List updates automatically according to the selected network modes.
Telephony: Whether the product supports voice telephony, default Yes. Affects the default selection of speech channels / control channels test items: when GSM is selected in Network and Telephony is Yes, C217 / C220 / C223 (control channels variants) are unselected by default.
