4294A

      The Agilent 4294A is precision impedance analyzer.Specifications describe the instrument's warranted performance over the temperature range of 0 °C to 40 °C (except as noted). Supplemental performance characteristics of 4294A are intended to provide information that is useful in applying the instrument by given non-warranted performance parameters. These are denoted as SPC (supplemental performance characteristics), typical, or nominal.Warm-up time must be greater than or equal to 30 minutes after power on for all specifications.
      The Agilent 4294A has some basic characteristics.Impedance parameters is |Z|-, R-X, Ls-Rs, Ls-Q, Cs-Rs, Cs-Q, Cs-D, |Y|-, G-B, Lp-G,Lp-Q, Cp-G, Cp-Q, Cp-D, Complex Z-Y, |Z|-Ls, |Z|-Cs, |Z|-Lp,|Z|-Cp, |Z|-Rs, |Z|-Q, |Z|-D, Lp-Rp, Cp-Rp.Configuration is four-terminal pair configuration.Connector type is four BNC (female) connectors. Can be converted to one port terminal using the Agilent 42942A Terminal Adapter (7-mm port) or 42941A Impedance Probe (3.5-mm port).When accuracy without Option 4294A-1D5.It's ±20 ppm (at 23 ±5 °C) ±40 ppm (at 0 to 55 °C).When accuracy with Option 4294A-1D5.It's ±0.13 ppm (at 0 to 55 °C).
      The Agilent 4294A has some paramater about voltage signal level.Range is 5 mVrms to 1 Vrms.Resolution is 1 mV.When accuracy at four-terminal pair port of the 4294A or 7-mm port of the 42942A.It's ±[(10 + 0.05 X f)% + 1 mV] (at 23 ±5 °C).When accuracy at measurement port of the 42941A, 16048G/H.It's ±[(15 + 0.1 X f)% + 1 mV] (at 23 ±5 °C).In the end there has a note:These characteristics apply when OPEN is connected to each port.Test signal level should be 0.5 Vrms when the measured impedance is 50 .Beyond 23 ±5 °C of temperature, test signal level setting accuracy is twice as bad as described.
