10 Spectrum Emission Mask Measurement
Meas Setup
The SCPI query returns values currently set to the relative power test limits.
Missing values are not permitted; that is, if you want to change values 2 and 6, you must send all values up
to 6. Subsequent values will remain as they were. The query for this parameter always returns 12 values.

Notes
Comma separated list of values.
OFFSet1 is for BTS, 2 for MS. Default is BTS.
You must be in the mode that includes SEM measurement to use this command. Use
:INSTrument:SELect to set the mode.
Couplings If the current mode is DVB-T/H, this value will be modified automatically according to the limit type
the output power of the transmitter which is less or more than 25W.
If the current mode is ISDB-T, this value will be modified automatically
according to the limit type.
If the current mode is WLAN and radio std is 802.11n, Rel Start limits will be set to following values
when frequency changed to above 5GHz:
0 dB, –20.00 dB, –28.00 dB, –40.00 dB, –40.00 dB, –40.00 dB, –40.00 dB, –40.00 dB, –40.00 dB,
–40.00 dB, –40.00 dB, –40.00 dB
Preset For modes (except MSR, LTEAFDD, LTEATDD and WLAN) without option N9060A–7FP, the preset
value is as follows.
SA: –30.00 dB, –30.00 dB, –30.00 dB, –30.00 dB, –30.00 dB, –30.00 dB
WCDMA: –30.00 dB, –30.00 dB, –30.00 dB, –30.00 dB, –30.00 dB, –30.00 dB|–33.73 dB, –34.00
dB, –37.50 dB, –47.50 dB, –47.50 dB, –47.50 dB
C2K: –45.00 dB, –45.00 dB, –55.00 dB, –55.00 dB, –55.00 dB, –55.00 dB|–42.00 dB, –54.00 dB, –
54.00 dB, –54.00 dB, –54.00 dB, –54.00 dB
WIMAX OFDMA: 0 dB, –25 dB, –32 dB, –50 dB, –50 dB, –50 dB
TD-SCDMA: –54.00 dB, –54.00 dB, –62.00 dB, –47.00 dB, –47.00 dB, –47.00 dB|–35.21 dB, –
49.00 dB, –44.00 dB, –44.00 dB, –44.00 dB, –44.00 dB
1xEVDO: –45dBc, –45.00 dB, –55.00 dB, –55.00 dB, –55.00 dB, –55.00 dB|–42dBc, –54.00 dB, –
54.00 dB, –54.00 dB, –54.00 dB, –54.00 dB
LTE, LTETDD: 0 dB, 0 dB, 0 dB, 0 dB, 0 dB, 0 dB|0 dB, 0 dB, 0 dB, 0 dB, 0 dB, 0 dB
Digital Cable TV: 0 dB, 0 dB, 0 dB, 0 dB, 0 dB, 0 dB |0 dB, 0 dB, 0 dB, 0 dB, 0 dB, 0 dB
When option N9060A–7FP is installed in these modes, the preset value of Offset G ~ L is the same
as the Offset F value.
