Easy operation ... To permit intuitive operation, the ¸SMJ100A is equipped with a large color display that provides an innovative GUI. The signal flow within the i ­nstrument is displayed in a block diagram, with each block representing a functional unit such as RF or baseband. The individual functions and settings are thus clearly assigned. All active components are highlighted in color, providing a quick and effective overview. The rotary knob plays a key role in ¸SMJ100A operation. It provides a quick means of navigating in the block diagram or in various menus and s ­ electing parameters...

A context-sensitive Help func- tion supports intuitive menus. The ticularly useful if you need information about the parameters available within Each edit window offers a tooltip func- tion that specifies the setting range of the selected parameter. If more detailed information is required, the Help func- tion comes in handy. It not only provides background information about various parameters, but also supports the pro- gramming of an automatic test setup with remote-control commands. The Help function also provides links to re- lated topics. Last but not least, the Help function includes the...

Signal quality To meet the demands of an all-purpose instrument, the basic RF parameters must be correct. SSB phase noise is one of the key figures. The ¸SMJ100A’s good performance with regard to SSB phase noise is due to its internal architecture, featuring a modern multiloop concept as well as a high-stability reference oscillator as standard. Typical SSB phase noise in the relevant frequency bands In addition to its basic RF characteristics, the instrument also offers high application-related performance. The adjacentchannel leakage ratio (ACLR) is an important key figure in 3GPP and especially...

In addition to the main mobile radio standards, the ¸SMJ100A – because of its large bandwidth and ample frequency coverage – is ideal for important wireless network standards such as WLAN IEEE 802.11 and WiMAX IEEE 802.16. Here, too, the ¸SMJ100A’s EVM capabilities underscore its standing as an all-purpose instrument. In addition, the ¸SMJ100A offers excellent performance with broadband signals, which is due to the high linearity of the baseband and the I/Q modulator. IEEE 802.11a Frequency: 5.7 GHz Signal Level: Sweep Mode: Single Trigger Mode: Burst Type: Direct Link Burst Modulation: Capture...

Full power in the baseband The flexible baseband generator in the strument. It includes a universal coder (for calculating signals in realtime) as well as an integrated arbitrary waveform generator with a memory depth of up to 64 Msamples, sufficient even for long complex test signals. Enhanced with a high system bandwidth of up to 80 MHz, current and future wireless applications. it provides up to four code channels in realtime. However, to generate a scenar- io with additional channels, further code channels can be added to the signal. In signals with different radio measure- ment channels...

The ¸SMJ100A can selectively generate bit errors and block errors in the coded signal. This allows the internal bit error ratio (BER) and block error ratio (BLER) calculations of a base station to be checked in line with TS 25.141. Rate matching In addition to conventional 3GPP signals, the flexible baseband also allows high speed downlink packet data access (HSDPA). Thus, the ¸SMJ100A already includes test model 5 as defined in TS 25.141 of the 3GPP specification. In addition to the Continuous mode, the ¸SMJ100A also permits the Packet mode for HSDPA channels in the downlink in line with TS 25.211....

Although third-generation mobile radio technology is already being implement- ed, the second generation with GSM/ EDGE is still highly important for many users. The internal GSM/EDGE option offers all burst types of the standard, in- cluding half-rate slots where both users are set individually. Moreover, multislot configurations are supported so that multiple slots can be assigned to one user with one common data source. of eight different slot levels, allowing a specific level to be assigned to each slot in a frame. Another important feature is the capability to change between GMSK and 8PSK...

In addition to the extensive functions in the mobile radio standards, the ¸SMJ100A also covers the wireless LAN standards IEEE 802.11a, IEEE 802.11b and IEEE 802.11g with complete channel coding. In the OFDM modes, all data rates of the IEEE 802.11a and IEEE 802.11g standards from 6 Mbps to 54 Mbps are supported. The same is true for the CCK mode with data rates from 1 Mbps to 11 Mbps, as well as for the PBCC mode where an optional expansion with data rates up to 22 Mbps has been added to the IEEE 802.11 g standard. The address of the specified receiver can be defined in the MAC header. Since...
