SMV03|Rohde&Schwarz SMV03|3G矢量信号发生器|罗德与施瓦茨|9kHz至3.3GHz
厂商名称： 德国罗德与施瓦茨Rohde&Schwarz
商品名称： SMV03宽带I/Q调制器|德国R/S|
商品型号： SMV03
* 宽带I/Q调制器
* 由于100 MHz的极宽的RF带宽，R&S SMV03是未来需要更高测试带宽的系统的理想选择
，如WLAN.
* 输出频率范围从9 kHz 到 3.3 GHz，分辨率为0.1Hz.
* 由于宽的频率范围覆盖了许多应用，一台仪器可用于许多不同的任务。
* 高达13 dBm、<0.5 dB的输出电平
R&S SMV03有足够的备用功率，因此测试设置引起的电平损失可以很容易得到补偿。同样，高
的电平精度使得它成为大量测试设置的理想选择：测量的不确定性来源于仪器和测试设置两
部份，因此小的信号发生器不确定性意味着可允许较大的测试设置容差。如果使用电平偏差
小的分析仪，从而允许较大的DUT容差，结果会是生产中不合格品的显著减少，效益立杆见影
。
使用电子衰减器的无中断电平设置
许多很复杂的电子设备对改变电平引起中断时产生的“过冲”（overshoots）非常敏感。R&S
SMV03因为使用了电子衰减器，改变电平设置时不会引起中断，从而使DUT免受此类过冲。
快速的频率和电平设置时间,SMV03回收
由于使用了合成器设计方法， R&S SMV03具有极低的设置时间，从而成为速度至上的生产中
的理想选择。这确实是R&S SMV03的优点：当打开IQ调制时，设置时间少于12 ms，而没
有IQ调制时，设置时间减小到10 ms以下。
The R & S SMV03 has sufficient standby power so that the level loss caused by the
test setup can easily be compensated. Also, high level accuracy makes it ideal
for a large number of test setups: the uncertainty of the measurement results
from both the instrument and the test setup, so small signal generator
uncertainty means that larger test setups can be tolerated Tolerance. If an
analyzer with a small level deviation is used, allowing for larger DUT
tolerances, the result will be a significant reduction in the production of
nonconforming products with immediate benefits.
Use the electronic attenuator's uninterrupted level setting,SMV03回收
Many sophisticated electronic devices are very sensitive to "overshoots" that
occur when interrupts are caused by changing levels. The R & S SMV03 uses an
electronic attenuator to prevent the DUT from overshooting by changing the level
setting without causing an interrupt.SMV03回收
Fast frequency and level setting times
Due to the use of synthesizer design methods, the R & S SMV03 has a very low set
-up time, making it ideal for speed-first production. This is indeed one of the
advantages of the R & S SMV03: When IQ modulation is turned on, the setup time is
less than 12 ms, without IQ modulation, the settling time is reduced to less than
10 ms.
