The male connector end is a NEMA type connector, and the female connector end is a C.E.E. type connector that mates with the 5340A rear panel power connector. Connect the power cable to a power source receptacle with a NEMA grounded third conductor.
DIGITAL INPUT/OUTPUT. Associated with this connector are six slide switches used to address the instrument. A 5340A can be addressed to either send output data (TALK) or to accept program information (LISTEN). For the purposes of the Option 011 description, several terms are defined as follows: A TALKER is the sender of information on the bus.
“output ONLY I F addressed”, the 5340A sets SRQ high at all times. When SRQ is high, service is not being requested. If two or more 5340A’s are connected to the bus and one of them sets SRQ low, the controller must go through a process of elimination to determine which one requested service.

Installation and Remote Programming d. ATTENTION (ATN) ATN is used by a controller to address a 5340A. The 5340A monitors ATN at all times. When ATN is low, all 5340A’s connected to the bus interpret the information on the data lines’ as a n address. They will handshake on the appropriate lines and will not drive the data lines.
When DAV is low, the states of data lines DIOl through D107 are unconditionally valid and may be accepted by all listeners at their own time. To allow for cable rise time, ringing, etc., the 5340A, when addressed to TALK, does not set DAV low until 2 ysec at its output connector.

Program information may be sent in any sequence. The 5340A will not make a measurement if there is either no signal in the selected range or there is one with a larger amplitude in some other range. When AUTO is selected, the 5340A automatically sweeps through all ranges until it finds the signal to be measured.

3-9. In a frequency counter, resolution can be defined as the value represented by the least, significant digit (LSD). In the 5340A, a maximum resolution of 1 Hz can be selected. Decade multiples of 1 Hz to 1 MHz are available. For example, with an input of 12,345,678 Hz, setting the RESOLUTION switch to the counter displays the 8 in the LSD.
3-12. The sample rate control sets the interval between measurements, but not the interval of the measurement. On the 5340A, the minimum sample rate is variable between approximately 50 milliseconds and 5 seconds. For 1 Hz RESOLUTION settings, a n additional 1 sec delay is incurred.
PARAGRAPH 3-22 FOR FULL EXPLANATION OF INPUT LEVELS. 3-22. The 5340A will function within specifications for signal inputs up to +7 dBm (5.012 milli- watts or 0.5006 volts into 50-ohms). Under no circumstance should the input level exceed 1-watt RF power or volts dc into 50-ohms, dc power).

VCO range. For signal inputs containing frequency modulation, see Figure 3-1 for the characteristics of the 5340A. 4-122. Transfer Phase Lock Loop 4-123. The transfer phase lock loop consists of A l l , A10, A9, and A8. This phase lock loop produces a n output (F2) that is related to F1 as follows: 20 kHz.
However for simplicity, a dc phase lock loop will be described followed by a n explanation of the type of phase lock techniques used in the 5340A. 4-128. A sampler looks at the input signal for a brief interval of time and charges a capacitor to the instantaneous voltage of the signal.
Model 5340A Theory of Operation A means must be provided to turn on the diodes periodically and this is achieved by biasing the diodes into conduction by a sampler driver. Assume that a positive pulse is injected into point A and a negative pulse into point by the generators.
Model 5340A Theory of Operation 4-136. As shown in Figure 4-49, sampling occurs at the zero crossing of the input signal, and the sampler output is zero volts. When the sampler output goes positive, it indicates that the sampl- ing occurs later than the correct time. This generates a n error signal to increase the sampling frequency so that sampling occurs at the zero crossing.
Model 5340A Theory of Operation 4-146. Q1B is a current source for Q1A to maintain the proper DC level for the input to U1. Varying R10 changes the DC level on the drain of Q1B. Q1A is a unity gain amplifier that presents a high input impedance to 54.
Model 5340A Theory of Operation A negative level a t pin 8 turns U2 and U4 off which turns off Q1. Q1 determines when the search ramp signal is routed to DC Compensation Amplifier A7. The search ramp signal is derived from the search pulse signal which is supplied from Search Programmer A6.
Model 5340A Theory of Operation pulse is determined by R20 and C19. The multivibrator can be retriggered at any time during the 50 psec period to establish a new 50 psec pulse output. As long as the multivibrator is retrig- which the circuit operates.
Model 5340A Theory of Operation 4-172. U2 serves a s a summing amplifier for the phase detector output and the output of U4. The gain of U2 for the phase detector signal is 5 as set by R20 a n d R15. The gain for the output of U4 is 1 as determined by R20 and R13.
Model 5340A Theory of Operation 4-175. A10 VCO NO. 2 ASSEMBLY, 05340-60008 4-176. When the counter is in the search phase, the VCO (Figure 8-16) provides a n output which varies from -100 to 185 MHz. When phase lock occurs, the frequency of the VCO is held constant and used by other circuitry.
Model 5340A Theory of Operation 4-186. A13 LIMITER/AMPLIFIER ASSEMBLY, 05340-60010 4-187. Figure 8-19 shows the schematic diagram for A13. The Limiter/Amplifier input receives the 20 MHz output of Preamplifier No. at pin 10 and provides the necessary limiting action for automatic amplitude discrimination.
A. 4-204. Any 5340A that is wired for Option 001 will work when the standard oscillator is installed. This may be helpful in troubleshooting. To install Option 001 in a n instrument not so equipped, see Section VII: The 10544A is factory repairable only. Adjustment procedures are contained in Section V.
Model 5340A Theory of Operation 4-207. The sample rate circuitry consists of A19Q1, AlSUlA, A19U2E, R1, and R2. R1 and R2 are located off of the pc board on the main chassis. The sample rate circuitry determines the length of waiting time between measurements. At the end of a measurement, XAlgPlA(4) goes low, allowing A19C1 to be charged through and R2.
Page 93
Model 5340A Theory of Operation 4-219. Counter U3 identifies what digit is currently being shifted in the serial display. U21 compares this data with the RESOLUTION information and subtracts a “2” offset at the appropriate time during a phase lock measurement. For direct count measurements, a zero is subtracted, leaving the number unchanged.
Rate control will determine the delay until the next measurements. Sample rate delay can be terminated by a n ASCII “J”. 4-228. The 5340A can be reset externally by supplying a n ASCII “H” to U25. This turns on U9C, generating a reset through U9B. Moving resolution switch A27 between detents also generates a reset through U9A if local (front panel control) operation being used.
4-235. The purpose of these circuits is to determine if N is within its limits. There are six possible ranges of N for the 5340A. For each range, the instrument selects different passive components so as to obtain a particular gain for the Input Phase Lock Loop. When the instrument is in local control or in remote control and auto range, the signal at U14F pin 13 is High, enabling the N checking circuits.
Model 5340A Theory of Operation 4-243. For example, assume we are completing the step in the fifth symbol in Figure 5-4 marked “Done ? 14”. ROM U3 input on pins 14, 13, 12, 11, and 10 is LLHLH and will output LLHLHHLL on pins 9, 7, 6, 5, 4, 3, 2, and 1, respectively.
Model 5340A Theory of Operation into A23U20. Using range information and the resolution switch setting, A19 determines when the “2” must be inserted as the eight columns of BCD information are shifted into A24. 4-254. U21A and U21B are activated for addition and U18D is used for subtraction. The carry information from U19B is sent into the carry input of the first BCD adder U10.
Model 5340A Theory of Operation 4-265. A26 BLANKING ASSEMBLY, 05340-60037 4-266. The Blanking Assembly (Figure 8-32) is controlled by logic circuits on A25 and controls the +175V supply to the display tube(s) that require blanking thus suppressing insignificant zeroes. For example, with a TTL low on the emitter of Q5, Q5 conducts to turn on QlO which in turn supplies +175V to the display tube.
4-275. +5 VOLT RF REGULATOR (PART OF A32). To prevent drift and instability in the RF circuits of the 5340A, tKe'+b volt RF regulator in A32 (Figure 8-34) uses a preregulator to achieve the required regulation and low ripple voltage. A32CR1 and A32CR2 establish a con- stant current through A32QV and A32CR4.
Model 5340A Theory of Operation 4-276. In the event that the +15 volt reference fails or falls below 11 volts, A32CR3 conducts to turn off A32Q2 thereby disabling the supply. This prevents A32U1 from locking in the off position. The series pass transistor in A32U1 drives A32Q5 to handle the larger current require- ments of the regulator.
4-284. The -5 volt regulator assembly (Figure 8-34) consists of two supplies, one for the RF circuits (-5V) in the 5340A and the other for the digital circuits (-DG). The supply for the RF circuits provides about 190 milliamperes and the digital supply provides approximately 1.1 amperes.
5-11. BLOWER FAN CONFIGURATION 5-12. The cooling fan in the 5340A is a n exhaust fan, not a n intake type. The fan discharges air out of the rear of the instrument. If the flow of air was reversed, the heat generated by the fan would preheat the intake air and tend to raise the internal temperature of the instrument.
