Agilent Technologies 85107B Sources, 8510-dedicated sources, 8360 general purpose synthesizers

Sources

The RF or microwave signal source in a VNA measurement system provides the incident signal used to stimulate the device-under-test (DUT). The DUT responds by reflecting part of the incident and transmitting the remaining part. By sweeping the frequency of the source, the frequency response of the DUT can be determined.

There are two types of sources available; the General Purpose (GP) 8360 series synthesized sweepers (836x0B) and the 8510-dedicated 8360 series synthesized sweepers (836x1B). Note: All 8360A synthesizers have been replaced by 8360B synthesizers.

Dedicated sources, such as the 836x1B shown in Table 4, are optimized for use in the 8510 network analyzer systems. They are configured without modulation capabilities or front panel keyboards. These sources include a 1 Hz frequency resolution and rear-panel output connectors.

Table 4. 8510-dedicated sources

Product1	Frequency range
83621B	45 MHz to 20 GHz
83631B	45 MHz to 26.5 GHz
83651B	45 MHz to 50 GHz

For applications that require modulation capabilities, such as pulsed-RF measurements, the required source is a general purpose 836x0B synthesized sweeper, shown in Table 5. Order Option 004 to obtain rear panel connectors, and Option 008 for 1 Hz frequency resolution.

Table 5. 8360 general purpose synthesizers

Product1	Frequency range
83620B	10 MHz to 20 GHz
83622B	2 GHz to 20 GHz
83623B	10 MHz to 20 GHz (high power)
83624B	2 GHz to 20 GHz (high power)
83630B	10 MHz to 26.5 GHz
83640B	10 MHz to 40 GHz
83650B	10 MHz to 50 GHz

1.Although general purpose 8360 series synthesized sweepers (836x0B) can be used in place of the 8510-dedicated 8360 series synthesized sweepers (836x1B), the following options are typically recommended: Option 004 (rear panel connectors) and Option 008 (1-Hz frequency resolution). These options are standard in the 8510-dedicated 8360 series synthesized sweepers.

Mixed sources: While mixing synthesized series is acceptable in multiple-source applications, the following areas must be considered:

•RF source = 8340, LO source = 8340, system performance will be degraded substantially.

•RF source = 8340, LO source = 8360, better system performance

•RF source = 8360, LO source = 8360, faster step frequency measurements. Using the 8340 as either the RF source or the LO source will more than double the measurement time.
