TEKTRONIX 7A18A Dual Trace Amplifier Plug-in

Tektronix 7A18A Dual-trace plug-in amplifier for the 7800, 7900 and 7100 Series mainframes. Bandwidth - Dc Coupled: 75 MHz (5 mV/div to 5 V/div). Ac Coupled: 10 Hz or less to 75 MHz (5 mV/div to 5 V/div). Deflection Factor - Calibrated: 5 mV/div to 5 V/div in ten steps (1 -2-5 sequence). Accuracy is within 2% with gain adjusted to 10 mV/div. Uncalibrated: Variable continuously between steps to a maximum of at least 12.5 V/div. Input R and C: 1 M-ohm within 2%; 20 pF. Maximum Input Voltage - Dc Coupled: 250 V (dc + peak ac), ac component 500 V p-p maximum, 1 kHz or less. Ac Coupled: 500 V (dc + peak ac), ac component 500 V p-p maximum, 1 kHz or less. Dc Stability - Drift with Ambient Temperature (Line Voltage Constant): 0.01 div/C. Drift with Time (Ambient Temperature and Line Voltage Constant): 0.02 div in anyone minute after one hour warm-up. Displayed Noise - 0.06 div or less. Common-Mode Rejection Ratio (Add, CH 2 Invert) - At least 10:1, dc to 50 MHz. Option 06, Dc Offset - Allows small signals riding on larger signals, such as power supply ripple, to be analyzed. Separate Channel 1 and Channel 2 variable offset controls are concentric with the position controls replacing the identify push-buttons of the standard 7A18A. The ac-dc ground switch of each channel is expanded to accommodate a fourth position for dc offset.

*This is a Web introductory price for one calibration of the TEKTRONIX 7A18A. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Average Power
Average power means that the energy transfer rate is to be averaged over many periods of the lowest frequency involved. For a CW signal, the lowest frequency and highest frequency are the same, so average power and power are the same. For an amplitude modulated wave, the power must be averaged over many periods of the modulation component of the signal as well.

Dynamic range
Dynamic range the ratio of a specified maximum level of a parameter, such as power, current, voltage or frequency, to the minimum detectable value of that parameter.

Modulation
Modulation is the process by which the characteristic of one wave (the carrier) is modified by another.

Repeatability
Repeatability is the variation in a number of repeated measured quantities when measurement conditions are changed and restored. The value corresponds to half the spread between the minimum and maximum value measured.
