Information

MODEL 22 Model 22 is a closed-loop, frequency stabilized, sweep/function Generator. Both short term and long term frequency accuracy is 0.09% over its 10OjiHzto 11 MHz frequency span. Modes are continuous, triggered, gated, sweep set, continuous sweep and triggered sweep. Output levels are to 20V peak-to-peak (10 Vp-p into 50Q). Waveforms are sine, triangle, square, ramp up, ramp down, and dc. Above 1.1 kHz waveforms are analog generated; below, waveforms are digitally synthesized. An LCD display shows frequency (31/2 digits plus unit of measure) and annunciators that indicate selected operating modes, etc. The waveform output circuit is protected from accidental application of high voltage to the BNC connector. 1.2 SPECIFICATIONS 1.2.1 Versatility Waveforms A bidirectional pushbutton switch selects sine, triangle, square and dc and for frequencies on or below the 1,100 kHz range, ramp up and ramp down. Operational Modes Continuous: Generator runs continuously at selected frequency. Continuous frequency and sweep start frequency set with Frequency Course and Fine controls. Triggered: Generator is quiescent until triggered by external signal or manual trigger, then generates one complete waveform cycle at selected frequency. Gated: As triggered mode, except output continues for duration of gate signal. Last waveform started is completed. Set: Generator runs continuously at sweep stop frequency set by Sweep Set control. Sweep stop frequency is displayed. Sweep: Generator frequency is swept from the start frequency limit set by the Frequency control to the stop frequency limit set by the Sweep Set control in a continuously occurring sweep. Sweep Time and lines logarithmic sweep are selectable. Frequency Range 100 µHz to 11 MHz in 9 overlapping decade ram Range switching with bidirectional switch with frequency digits, decimal and units displayed on LCD display. E decade range capable of 1100:1 frequency change controlled by the Frequency Course and Fine control. Function Output Waveform amplitude variable over a 20 dB range 20 Vp-p (10 Vp-p into 50Ω) at Function Out. Wave also present at Function Out (-20 dB) with a fixed 2< attenuation relative to the Function Out for a full of amplitude range. Peak output current is 1OOmA minimum at Function Out. Source impedance of both puts is 50Ω. DC Offset and DC Output Waveform offset and dc output variable with DC 01 control with off position for calibrated zero offset. Function Out is ± 10V maximum (± 5V into 50Q) as offs* Vdc output. Signal peak plus off set limited to ± 10V(: into 50Q). DC offset plus waveform attenuated proportionately at Function Out (-20 dB). Sync Output TTL pulse (50% duty cycle) at Generator frequency drive 10 LS TTL loads. VCG — Voltage Controlled Generator Up to 1100:1 frequency change with external 0 to ±5V signal applied to VCG IN connector. Upper and lower frequencies limited to maximum and minimum of selected range. Input impedance is 5kQ and maximum slew rate is 0.1 V/µs. VCG IN is disconnected when the Stabilizer is enabled. Trigger and Gate External TTL compatible signal at Trig In BNC triggers or gates Generator output when Generator is in trigger, gate or triggered sweep mode. Generator triggers on positive edge of input or gates on for duration of high level input. External signal pulse width is 50 ns minimum with a maximum repetition rate of 5 MHz. Stabilizer When selected, the Generator frequency is stabilized at the displayed frequency to a crystal-controlled reference. When the stabilizer is on, long term frequency stability is corrected to the displayed frequency over the entire operating temperature range of 0 to "f-50°C. The stabilizer is automatically turned off when the mode is taken out of continuous or when Log frequency is enabled. Display 1100 count LCD frequency display with frequency ranging units (mHz, Hz, kHz, and MHz) and a floating decimal point. Annunciators indicate selection of waveform, stabilizer status, Generator mode, sweep time and linear or logarithmic sweep. Time Symmetry Square waveform variation from 1100 to 100 counts on display less than: ± 0.1 % to 1.100 kHz (across bottom five specified ranges), ±1 % to 110.0 kHz, ±5% to 11.00 MHz. 1.2.3 Amplitude Precision Sine Variation with Frequency Less than: ± 0.2 dB on ail ranges up through the 110.0 kHz range, ±1.5 dB to 11.00 MHz. Referenced to 1 kHz. 1.2.4 Waveform Characteristics Sine Distortion <0.5% THD up through the 11.00 kHz range. <1.0% THD on 110.0 kHz range. All harmonics 40 dB below fundamental on 1.100 MHz range, and 28 dB below fundamental on 11.00 MHz range. Square Wave Rise/Fall Time: <22 ns Total Aberrations: Each peak <5% of p-p amplitude. Triangle Linearity >99% to 110.0 kHz. Sweep Generator Sweep Mode: Linear or logarithmic, up to 3 decades. Sweep Time: Selectable (in seconds) .01 ,.1,1 and 10. Sweep Output: Output voltage at sweep out connector proportional to the sum of Frequency control, internal sweep voltage and external VCG In voltage. Scale factor is 0 to -f 5V (open circuit) linear voltage change from bottom to top frequency of a range. Source impedance is 600Q for driving horizontal axis of Oscilloscope or recording equipment. Sweep Width: Up to 1100:1 linear or logarithmic.
