The Boonton 72C, 100 kHz analog meter is recommended for series capacitance measurements on very low capacitance junctions where normal series loss can cause the Q of the junction capacitance to fall well below 10 at 1 MHz. In this instance, using 72C takes advantage of the fact that the Q of the cpacitor with series loss is inversely proportional to frequency and therefore ten times higher at 100 kHz then at to 1 MHz.

The Agilent 70908A RF section provides fundamentally mixed 100 Hz to 22 GHz broadband input conversion for the Agilent 71210C spectrum analyzer and the Agilent 71400C lightwave signal analyzer. Fundamental mixing provides a means of achieving unprecedented sensitivity for microwave measurements and for high speed lightwave modulation rates. This sensitivity allows you to reduce microwave spurious test times from days to hours. Improved sensitivity also improves second and third order dynamic range. Excellent dynamic range is obtained with an analyzer with both good sensitivity and good distortion performance (TOI and SOI). The internal preselector dynamically tracks the analyzer’s tuning. This means the preselector is continuously peaked, which saves you time and provides excellent amplitude accuracy. The 70908A also contains a 70 dB step attenuator variable in 10 dB steps. Option H25 provides a 5 dB step attenuator. The 321.4 MHz IF output allows you to access the converted RF signal. You can then detect and display this signal on external equipment.

The Agilent 70907B external mixer interface module (EMIM) is the interface needed to use the Agilent 11974 series preselected millimeter mixers with Agilent 70000 modular spectrum analyzers. The 70907B provides the 11974 mixers with a swept LO signal and a tune and span signal. The 11974 mixers return an IF signal to the 70907B, where it is converted to 21.4 MHz and output to an IF module. The 70907B external mixer interface module is also compatible with the 11970 series millimeter mixers, which extend to 110 GHz, and with millimeter mixers from other manufacturers, which extend to 325 GHz. (Other mixer series are not preselected.) An Agilent 70907A can be upgraded to the 70907B with the Agilent 70907A K74 upgrade kit. The kit can be installed by the customer in about one hour. The Agilent 70000 LO module (70900A or B) must meet certain date code requirements.

The Agilent 70905B RF section provides the broadband inputs for the spectrum analyzers. The RF section converts the input signals to an intermediate frequency for further processing. This broadband, low noise mixer offers the performance needed to make high dynamic range measurements. The Agilent 70905B operates to 22 GHz and is used with the Agilent 70600A preselector module. In manufacturing environments where signals are known, you can bypass the preselector for better sensitivity and amplitude flatness. When unpreselected, an automatic signal identification routine returns the frequency of an unknown signal. Simply place a marker on a signal response. The 321.4 MHz output and input are available when the module is tuned above 2.7 GHz. This provides an unpreselected signal which can be demodulated or detected. The first LO auxiliary output allows operation with tracking generators and external mixer interface modules.

The Agilent 70902A provides narrow resolution bandwidths, from 10 Hz to 300 kHz and can be used in any of the configured systems. This intermediate frequency (IF) section provides signal processing elements required for spectrum analyzers and lightwave signal analyzers. The Agilent 70902A maximizes measurement speed using 10% incremental bandwidths. Wide bandwidths offer the most speed, whereas narrow bandwidths offer more resolution and sensitivity. The 10% incremental bandwidth steps offer you the best choice of bandwidth sizes. The bandwidths can also be changed in a 1, 3, 10 sequence. Calibrated logging amplifiers provide superb amplitude accuracy for the analyzers. The 3 MHz IF output on the Agilent 70902A allows connection to other instruments such as demodulators, digitizers, and oscilloscopes.

The Agilent 70900B is the master control module for the modular spectrum analyzers and surveillance receivers. It is also a component of the lightwave signal analyzers. The Agilent 70900B LO has two main functions in the Agilent 70000 spectrum analyzers: as the synthesized local oscillator (LO) and as the master control module for the system. As a spectrum analyzer local oscillator, it affects phase noise, stability, and frequency accuracy. The Agilent 70900B is the reason that the analyzer has excellent phase noise performance of -108 dBc/Hz at 10 kHz offset from the carrier. The synthesis technique has millihertz resolution for accurate frequency control. The fast tuning speed of the LO directly relates to the tuning speed of the analyzer. As the master control module, the Agilent 70900B determines system features, slave module control, command processing speed, and GPIB speed. The combination of hardware and processing power provides fast tuning for surveillance applications and automatic testing.
