R&S SMB Test Procedures Evaluation If the power < P — 0.41 dB noise the inherent noise power of the analyzer can be subtracted: Pnoise Wideband Noise If the power > P 0.41 dB noise the analyzer resolution is not sufficient for a precise measurement. The true result is in such case certainly more than 10 dB below the measured value.

Page 48: Level Data

R&S SMB Test Procedures Level Data Level Uncertainty Test method The level uncertainty is measured in two steps. First, the frequency response is measured at a fixed level with high frequency resolution. Then the level dependant uncertainty is measured at fixed frequencies over the specified range.
Page 49
Test Procedures R&S SMB Test method for low levels Test principle Low levels can only be measured using a frequency selective measurement instrument. Spectrum analyzers with digital IF are best suited for this measurement due to their low linearity error. The absolute accuracy of these analyzers is not sufficient for this measurement.
Page 50: Output Impedance Test Assembly

R&S SMB Test Procedures Output Impedance Test assembly «Test Assembly for Output Impedance (VSWR)» (page 1.5) Test method For the VSWR measurement of a source the effect of the level control must be taken into account. For this purpose, an auxiliary generator is used which transmits a wave with a slightly offset carrier frequency into the DUT.

Test Procedures R&S SMB Setting Time Test assembly Connect the spectrum analyzer (Table 1-1, item 18) to the RF connector of the DUT. Test method The spectrum analyzer is operated as a fast level meter in zero span. A controller transfers the start and the stop level via the IEC/IEEE bus. The analyzer is triggered by the positive edge on the EOI line of the IEC/IEEE bus.

The main units are: •…
Page 141: Rf Board

Instrument Design and Function Description R&S SMB RF Board The RF BOARD contains the complete measuring hardware of the instrument. The RF and LF signals are generated and modulated on the module. The output level is controlled by a level control loop controlling the level before the step attenuator.
Page 142: Rf Synthesizer/ Dds Module

R&S SMB Instrument Design and Function Description RF Synthesizer/ DDS module The 200 MHz signal of the TCXO provides the system clock for the DDS module. The RF output frequencies from 9 kHz to 23.4375 MHz are generated directly by the DDS. In this mode all the modulation is done fully digital.
Page 143: Automatic Level Control

At the RF output of the RF Board a reverse power protection circuitry detects RF power fed into the RF Board from outside the instrument. To protect the SMB100A against damage a relay disconnects the RF output, when a reverse power of more than approximately 34 dBm is detected. In standby or power off mode this relay is also in off state to protect the RF output of the instrument from damage.
Page 144: Switching Regulators

The diagnostic ADC is used for measuring the voltages in the unit. These voltages are used for internal adjustments and the ALC S&H mode of the SMB100A. Additionally the failure diagnostic of the instrument is carried out by the use of ADC.
Page 145: Stereo/Rds Coder Module

Instrument Design and Function Description R&S SMB Stereo/RDS Coder module For support of FM Stereo modulation an optional Stereo/RDS Coder module can be installed. The Coder accepts analog signals from the external audio input rear connectors or generated by the RF-Board LF Generator.
Page 146: Troubleshooting

R&S SMB Troubleshooting Troubleshooting The purpose of these troubleshooting instructions is to help to trace down malfunctions to board level. The instrument can thus be made ready for use again by means of board replacement. If error tracing doesn’t show clear results, we recommend that you ship your instrument to our experts in the service centers (see address list) for module replacement and further error elimination.

After briefly pressing the ON/OFF button on the front panel, the CPU performs a normal system shutdown and then powers off the power supply via pin 13 of the power supply connector.
Page 149
Troubleshooting R&S SMB The instrument can also be switched off by means of the temperature monitoring circuit on the Basis Board. If the temperature sensor on the Basis Board detects an over temperature (e.g. in the event that a fan fails), the power supply is switched off via pin 13 of the power supply connector. It can only be switched on again, after cooling down.
