WLAN TX Measurements (Option K91 / K91n) R&S <strong>ZVL</strong>-<strong>K1</strong><br />

Standard (General Settings dialog box)<br />

Displays a list of all installed standards to select <strong>the</strong> wireless LAN standard. This is necessary to<br />

ensure that <strong>the</strong> measurements are per<strong>for</strong>med according to <strong>the</strong> specified standard with <strong>the</strong><br />

correct limit values and limit lines.<br />

� Remote: CONF:STAN 0<br />

Frequency (General Settings dialog box)<br />

Specifies <strong>the</strong> center frequency of <strong>the</strong> signal to be measured. If <strong>the</strong> frequency is modified, <strong>the</strong><br />

Channel No field is updated accordingly.<br />

� Remote: FREQ:CENT 100MHz<br />

Channel No (General Settings dialog box)<br />

Specifies <strong>the</strong> channel to be measured. If <strong>the</strong> Channel No field is modified, <strong>the</strong> frequency is<br />

updated accordingly.<br />

� Remote: CONF:CHAN 9<br />

Signal Level (General Settings dialog box)<br />

Specifies <strong>the</strong> expected mean level of <strong>the</strong> RF input signal. If an automatic level detection<br />

measurement has been executed <strong>the</strong> signal level (RF) is updated.<br />

For all standards o<strong>the</strong>r than IEEE 802.11b & g (Single Carrier), <strong>the</strong> reference level is set 10 dB<br />

higher than <strong>the</strong> signal level (RF) because of <strong>the</strong> expected crest factor of <strong>the</strong> signal. For<br />

standards IEEE 802.11b & g (Single Carrier), <strong>the</strong> reference level is set to <strong>the</strong> signal level (RF).<br />

� Remote: CONF:POW:EXP:RF 9<br />

Auto Lvl (General Settings dialog box)<br />

Activates or deactivates <strong>the</strong> automatic setting of <strong>the</strong> reference level <strong>for</strong> measurements.<br />

On The reference level is measured automatically at <strong>the</strong> start of each measurement<br />

sweep. This ensures that <strong>the</strong> reference level is always set at <strong>the</strong> optimal level <strong>for</strong><br />

obtaining accurate results but will result in slightly increased measurement times. For<br />

details about automatic level detection refer to chapter "Advanced Measurement<br />

Examples".<br />

Off The reference level is defined manually in <strong>the</strong> Signal Level field.<br />

� Remote: CONF:POW:AUTO 1<br />

� Remote: CONF:POW:AUTO:SWE:TIME 200MS<br />

Ext Att (General Settings dialog box)<br />

Specifies <strong>the</strong> external attenuation or gain applied to <strong>the</strong> RF signal. A positive value indicates<br />

attenuation, a negative value indicates gain. All displayed power level values are shifted by this<br />

value.<br />

� Remote: INP:ATT 30dB<br />
