|
||||||||||||||||||||||||||||||||||||||||
| Function | The 8756A processes and displays the demodulated 27.8 kHz signals from the HP 11664 detectors and the HP 85020 or 85027 bridges. |
| Dynamic Range | +10dBm to -50dBm in all three inputs (A, B, and R) |
| Dynamic Accuracy | dynamic accuracy of a single
channel measurement using HP 11664A/D/E Detector. Measurement taken
over +10 to -50dBm at 25°C and at 50 MHz. ± (0.1 dB + 0.01 dB/dB) from +10 to -40dBm. ± (0.2 dB + 0.02 dB/dB) from -40 to -50dBm. |
| Scale Resolution | 0.1, 0.2, 0.5, 1, 2, 5, 10 or 20 dB per division. Independently controlled for each measurement channel. |
| Reference Offset | offset level adjustable in 0.01 dB increments from -70.00 to +20.00dBm (absolute) or -90.00 to +90.00dB (ratio). |
| Resolution | |
| Vertical | 0.006dB for display. 0.01dB for "Display Cursor." |
| Horizontal | 401 points. |
| Adjustable Horizontal Resolution (101, 201 or 401 points) is available as Option H20. | |
| Sweep Time | minimum sweep time ³ 150 ms (50 ms with Opt. H20). |
| Averaging | 2, 4, 8, 16, 32, 64, 128, or 256 traces may be averaged. Independent control of each display channel. |
| Normalization | traces are stored and normalized to 0.006 dB resolution, independent of scale/division or offset. The horizontal resolution is 401 points. |
| Transfer Formats | data may be transferred as either ASCII strings (nominally 6 characters per reading) or as 16 bit integers. Readings may be taken at a single point or as an entire 401 point measurement trace. |
| Transfer Speed | ASCII format, trace: 800 ms
typical. ASCII format, point: 10 ms typical. Binary format, trace: 35 ms typical. Binary format, point: 5 ms typical. |
| Description | The 8756A System Interface is an HP-IB port used exclusively by the 8756A to control and extract information from a sweep oscillator and a digital plotter. |
| Sweep Oscillators | 8350B with RF plug-in, 8340B/8341B synthesized sweep oscillators. |
| Plotters | 7440A Opt. 002, 7475A Opt.002, 7550A Opt. 002, 9872C. |
| Power Requirements | 48 to 62 Hz, 115/230V ± 10%, typically 100 watts. |
| Dimensions | 178 H X 425.5 W X 451 mm D (7.0 X 16.75 X 17.75 in.) |
| Weight | Net, 15 kg (33 lb). Shipping, 20 kg (44 lb). |
